1. Product introduction

Fig. 1 CRE, CRIE and CRNE pumps

The CRE, CRIE and CRNE pumps are based on the

CR, CRI and CRN pumps.

CRE, CRIE and CRNE pumps belong to the so-called

E-pump family and are referred to as E-pumps.

The difference between the CR and CRE pump ranges

is the motor. CRE, CRIE and CRNE pumps are fitted

with an E-motor, i.e. a motor with built-in variable

frequency drive.

The E-pump motor is a Grundfos MLE motor.

The built-in frequency converter enables continuously

variable control of the motor speed. This means that

the pump can be set to operate at any duty point. The

purpose of continuously variable speed control of the

motor speed is to adjust the performance to a given

requirement.

CRE, CRIE, CRNE pumps are available with a

pressure sensor enabling the control of the pressure

on the outlet side of the pump.

The purpose of supplying the E-pumps with a pressure

sensor is to make the installation and commissioning

simple and quick. All other E-pumps are supplied

without sensor.

E-pumps without sensor are used when uncontrolled

operation (open loop) is required or when there is a

wish to fit a sensor at a later stage in order to enable:

• pressure control

• flow control

• level control of liquid in a tank

• temperature control

• differential pressure control

• differential temperature control.

E-pumps without sensor are also used when a remote

analog signal is connected to the setpoint input

terminal.

The pump materials are identical to those of the CR,

CRI and CRN pump ranges.

An E-pump is not just a pump, but a system which is

able to solve application problems or save energy in a

variety of pump installations. All that is required, is the

power supply connection and the fitting of the E-pump

in the pipe system, and the pump is ready for

operation.

The pump has been tested and pre-configured from

the factory. The operator only has to specify the

desired setpoint (pressure) and the system is

operational.

In new installations, the E-pumps provide a number of

advantages. The integrated variable frequency drive

has a built-in motor protection function which protects

both motor and electronics against overload. This

means that E-pump installations do not require a

motor-protective circuit breaker, but only a normal

short-circuit protection for the cable.

Fig. 4 Components of a Grundfos E-pump

Selecting an E-pump

Select an E-pump if the following is required:

• controlled operation, i.e. the consumption fluctuates

• constant pressure

• communication with the pump.

Adaptation of performance through frequency-

controlled speed control offers obvious benefits, such

as:

• energy savings

• increased comfort

• control and monitoring of the pump performance.

Applications

For further information about which pump version to

choose for a specific application or liquid, see Pumped

liquids on page 87.

Application examples

As discussed earlier, speed control of pumps is an

efficient way of adjusting pump performance to the

system.

In this section, we will discuss the possibilities of

combining speed-controlled pumps with PI controllers

and sensors measuring system parameters, such as

pressure, differential pressure and temperature. On

the following pages, the different options will be

presented through examples.

Constant-pressure control

A pump supplies tap water from a break tank to various

taps in a building.

The demand for tap water varies, and so does the

system characteristic, according to the required flow

rate. To achieve comfort and energy savings, we

recommend a constant supply pressure.

Fig. 5 Constant-pressure control

As appears from fig. 5, the solution is a speed-

controlled pump with a PI controller. The PI controller

compares the required pressure, pset, with the actual

supply pressure, p1, measured by a pressure

transmitter PT.

If the actual pressure is higher than the setpoint, the PI

controller reduces the speed and consequently the

performance of the pump until p1 = pset. Figure 5

shows what happens when the flow rate is reduced

from Qmax. to Q1.

The controller reduces the speed of the pump from nn

to nx in order to ensure that the required outlet

pressure is p1 = pset. The pump ensures that the

supply pressure is constant in the flow range of 0 to

Qmax. The supply pressure is independent of the level

(h) in the break tank. If h changes, the PI controller

adjusts the speed of the pump so that p1 always

corresponds to the setpoint.

Constant-temperature control

Performance adjustment by means of speed control is

suitable for a number of industrial applications. Figure

6 shows a system with an injection molding machine

which must be water-cooled to ensure high quality

production.

Fig. 6 Constant-temperature control

The pump will be operating at a fixed system

characteristic. The controller will ensure that the actual

flow rate, Q1, is sufficient to ensure that tr = tset.

The machine is cooled with water at 59 °F (15 °C) from

a cooling plant. To ensure that the molding machine

runs properly and is cooled sufficiently, the return-pipe

temperature has to be kept at a constant level, tr = 68

°F (20 °C). The solution is a speed-controlled pump,

controlled by a PI controller. The PI controller

compares the required temperature, tset, with the

actual return-pipe temperature, tr, which is measured

by a temperature transmitter TT. This system has a

fixed system characteristic, and therefore the duty

point of the pump is located on the curve between Qmin

and Qmax. The higher the heat loss in the machine, the

higher the flow of cooling water needed to ensure that

the return-pipe temperature is kept at a constant level

of 68 °F (20 °C).

Terminal box positions

As standard, the terminal box is fitted on the inlet side

of the pump.

Fig. 10 Terminal box positions

Ambient temperature

If the ambient temperature exceeds the above

maximum ambient temperatures or the pump is

installed at an altitude exceeding 3280 ft (1000 m), the

motor must not be fully loaded due to the risk of

overheating. Overheating may result from excessive

ambient temperatures or high altitudes.

In such cases, it may be necessary to use a motor with

a higher rated output.

Viscosity

The pumping of liquids with densities or kinematic

viscosities higher than those of water will cause a

considerable pressure drop, a drop in the hydraulic

performance and a rise in the power consumption.

In such situations, fit the pump with a larger motor. If in

doubt, contact Grundfos.

Installation altitude

Installation altitude is the height above sea level of the

installation site. Motors installed up to 3280 ft (1000 m)

above sea level can be loaded 100 %.

Motors installed more than 3280 ft (1000 m) above sea

level must not be fully loaded due to the low density

and consequently low cooling effect of the air.

2. MLE technical data

Grundfos MLE motors are equipped with NEMA

standard C-face flanges.

Grundfos MLE motors are recognized under the

Component Recognition Program of Underwriters

Laboratories Inc. for the United States and Canada.

MLE motors are equipped with a reinforced bearing

system with locked bearings at the drive end, either a

deep-groove ball bearing or an angular-contact

bearing depending on the motor model.

This ensures an even uptake of the load in order to

maximize the lifetime of the bearings, which are

guaranteed for a minimum of 18,000 hours service life.

At the non-drive end, the motors are fitted with

bearings with axial clearance in order to meet

production tolerances while allowing for thermal

expansion during motor operation. This ensures

trouble-free operation and long life.

3. Control of E-pumps

CRE, CRIE and CRNE pumps are the ideal choice for

a number of applications characterized by a demand

for variable flow at constant pressure. The pumps are

suited for water supply systems and pressure boosting

as well as for industrial applications.

Depending on the application, the pumps offer energy

savings, increased comfort and improved processing.

E-pumps in the service of industry

The industry uses a large number of pumps in many

different applications. Demands on pumps in terms of

pump performance and mode of operation make speed

control a must in many applications.

E-pumps are ideal for and often used in the situations

listed below.

Constant pressure

• Water supply

• washing and cleaning systems

• distribution from waterworks

• humidifying systems

• water treatment systems

• process boosting systems, etc.

Example: Within industrial water supply, E-pumps with

integrated pressure sensor are used to ensure a

constant pressure in the pipe system. From the sensor,

the E-pump receives inputs about changes of pressure

as a result of changes in the consumption. The E-

pump responds to the input by adjusting the speed

until the pressure is equalized. The constant pressure

is stabilized once more on the basis of the preset

setpoint.

Constant temperature

• Air-conditioning systems in industrial plants

• industrial cooling systems

• industrial freezing systems

• casting and molding tools, etc.

Example: In industrial freezing systems, E-pumps with

temperature sensor increase comfort and lower

operating costs compared with pumps without a

temperature sensor.

An E-pump continuously adapts its performance to the

changing demands reflected in the differences in

temperature of the liquid circulating in the freezing

system. Thus, the lower the demand for cooling, the

smaller the quantity of liquid circulated in the system

and vice versa.

Constant level

• Boiler feed systems

• condensate systems

• sprinkler irrigation systems

• chemical industry, etc.

Example: In a steam boiler, it is important to be able to

monitor and control pump operation to maintain a

constant level of water in the boiler.

By using an E-pump with level sensor in the boiler, it is

possible to maintain a constant water level.

A constant water level ensures optimum and cost-

efficient operation as a result of a stable steam

production.

Dosing applications

• Chemical industry, i.e. control of pH values

• petrochemical industry

• paint industry

• degreasing systems

• bleaching systems, etc.

Example: In the petrochemical industry, E-pumps with

pressure sensor are used as dosing pumps.

The E-pumps help to ensure that the correct mixture

ratio is achieved when more liquids are combined.

E-pumps functioning as dosing pumps improve

processing and offer energy savings.

E-pumps in commercial building

services

Commercial building services use E-pumps to maintain

a constant pressure or a constant temperature based

on a variable flow rate.

Constant pressure

Water supply in high-rise buildings, such as office

buildings and hotels.

Example: E-pumps with pressure sensor are used for

water supply in high-rise buildings to ensure a constant

pressure even at the highest draw-off point.

As the consumption pattern and thus the pressure

changes during the day, the E-pump continuously

adapts its performance until the pressure is equalized.

Constant temperature

• Air-conditioning systems in hotels, schools, etc.

• building cooling systems, etc.

Example: E-pumps are an excellent choice for

buildings where a constant temperature is essential.

E-pumps keep the temperature constant in air-

conditioned, high-rise glass buildings, irrespective of

the seasonal fluctuations of the outdoor temperature

and various heat impacts inside the building.

Control options

It is possible to communicate with CRE, CRIE, CRNE

pumps via the following platforms:

• control panel on the pump

• Grundfos GO Remote

• central management system.

The purpose of controlling an E-pump is to monitor and

control the pressure, temperature, flow rate and liquid

level of the system.

Control panel on the pump

The control panel on the E-pump terminal box makes it

possible to change the setpoint settings manually.

Central management system

Communication with the E-pump is possible even if the

operator is not present near the E-pump.

Communication is enabled by connecting the E-pump

to a central management system. This allows the

operator to monitor the pump and to change control

modes and setpoint settings.

Control modes for E-pumps

Grundfos CRE, CRIE and CRNE pumps are available

in two variants:

• CRE, CRIE and CRNE with integrated pressure

sensor

• CRE, CRIE and CRNE without sensor.

CRE, CRIE and CRNE with integrated

pressure sensor

Use CRE, CRIE and CRNE pumps with integrated

pressure sensor in applications where you want to

control the pressure after the pump, irrespective of the

flow rate. For further information, see Control of E-

pumps on page 18.

Signals of pressure changes in the pipe system are

transmitted continuously from the sensor to the pump.

The pump responds to the signals by adjusting its

performance up or down to compensate for the

pressure difference between the actual and the

desired pressure. As this adjustment is a continuous

process, a constant pressure is maintained in the pipe

system.

4. Advanced use of MLE motors

Introduction

Grundfos MLE motors have many features for the

advanced user.

Grundfos three-phase MLE motors have features such

as bearing monitoring, standstill heating, stop function,

signal relays, analog sensors and limit exceeded.

These features give a unique opportunity to customize

the E-pumps.

PC Tool E-products gives access to most of the

settings available in the products, as well as the

possibility of logging and viewing data.

All of these features are described below.

Bearing monitoring

Bearing monitoring is a built-in function indicating the

time to relubricate or replace the bearings of the MLE

motor. The relubrication feature is only available for

three-phase pumps of 15-30 HP.

Purpose and benefits

The purpose of this function is to give an indication to

the user when it is time to relubricate or replace the

motor bearings. This is important information for

maintenance planning.

Bearing monitoring provides these benefits:

• The bearing can be relubricated at the right time

according to the manufacturer's recommendations.

• Maximum life of the motor bearings is obtained.

• Maintenance intervals are based on the operating

conditions of the bearings.

• No worn-down or damaged bearings, and

consequently no costly down-time, due to overseen

maintenance.

Description

When the bearing monitoring function determines that

it is time to relubricate the bearings, the user will

receive a warning via PC Tool E-products, a bus or a

relay.

When the bearings have been relubricated, a certain

number of times, the warning function will inform the

user to replace the bearings.

The number of relubrications before bearing

replacement is set by Grundfos.

Technical description

The bearing monitoring function is available on two

levels for calculating the relubrication interval, basic

and advanced:

Standstill heating

Standstill heating is a feature ensuring that even

during standstill periods the motor windings have a

certain minimum temperature.

Purpose and benefits

The purpose of this function is to make the MLE motor

more suitable for outdoor installation. During standstill

periods, there is a need to keep the motor temperature

higher than the ambient temperature to avoid

condensation in and on the motor.

Traditionally this issue has been solved by using an

anti-condensation heater on the stator coil heads. Now

Grundfos provides this feature by means of a special

function within the MLE motor and terminal box.

The MLE motor has standstill heating included. An

external heater on the stator coil is not necessary.

Applications

This function is especially suitable in outdoor

applications and at installation sites with fluctuating

temperatures.

Description

The working principle is that AC voltage is applied to

the motor windings. The applied AC voltage will ensure

that sufficient heat is generated to avoid condensation

in the motor. The terminal box is kept warm and dry by

the heat generated via the power supply. However, it is

a condition that the terminal box is not exposed to

open air. It must be provided with a suitable cover to

protect it from rain.

Bearing monitoring function

Basic level

Calculation of relubrication intervals based on motor

revolutions

The basic level is a standard feature of the 15-30 HP basic

controller and no special functional module is required.

Advanced level (only 15-30 HP)

Calculation of relubrication intervals based on motor

revolutions and bearing temperature

Note: The advanced-level function requires the following:

• The extended functional module must be fitted in the MLE

motor.

• Temperature sensors must be fitted at the drive end and at

the non-drive end of the motor.

CRE, CRIE, CRNE 4

Outdoor installation

According to UL 778 and C22.2 No 108-14, pumps that

are intended for outdoor use must be marked

enclosure type 3, and the product must be tested at a

rated surface temperature down to -31 °F (-35 °C). The

MLE enclosure is approved for type 3 or 4 and a rated

surface temperature down to 32 °F (0 °C), and thus

only for indoor use in UL 778 and C22.2 No 108-14

pump applications. See the installation and operating

instructions for additional details.

Stop function

The stop function ensures that the pump is stopped at

low or no flow. The function is also called low-flow stop

function.

Purpose and benefits

The purpose of the stop function is to stop the pump

when low flow is detected.

The stop function provides these benefits:

• The energy consumption is optimized and the

system efficiency is improved.

• Unnecessary heating of the pumped liquid which

damages pumps is avoided?

• Wear of the shaft seals is reduced.

• Noise from operation is reduced.

Applications

The stop function is used in systems with periodically

low or no consumption thus preventing the pump from

running against closed valve.

Operating conditions for the stop function

A pressure sensor, a check valve, and a diaphragm

tank are required for the stop function to operate

properly.

Note: The check valve must always be installed before

the pressure sensor. See fig. 21 and fig. 22.

Fig. 21 Position of the check valve and pressure sensor in

system with suction lift operation

Fig. 22 Position of the check valve and pressure sensor in

system with positive inlet pressure

When low flow is detected, the pump is in start/stop

operation. If there is flow, the pump will continue

operating according to the setpoint. See fig. 23.

Fig. 23 Constant pressure with stop function. Difference

between start and stop pressures (∆H)

Diaphragm tank

The stop function requires a diaphragm tank of a

certain minimum size. The tank must be installed near

the pump outlet, and the precharge air pressure must

be 0.7 x setpoint.

Recommended diaphragm tank size:

If a diaphragm tank of the above size is installed in the

system, additional adjustment is unnecessary. If the

tank installed is too small, the pump will start and stop

often. Tank size will influence at which flow rate the

system will go into start/stop operation.

Description

The low-flow stop function can operate in two different

ways:

• by means of an integrated low-flow detection

function

• by means of an external flow switch connected to

the digital input.

Low-flow detection function

• The low-flow detection function will check the flow

rate regularly by reducing the speed for a short

time. A small change in pressure or no change in

pressure means that there is low flow.

Low-flow detection with flow switch

• When a flow switch detects low flow, the digital input

will be activated.

Contact Grundfos for further information.

Dry-running protection

This function protects the pump against dry running.

When lack of inlet pressure or water shortage is

detected, the pump will be stopped before being

damaged.

Lack of inlet pressure or water shortage can be

detected with a switch connected to a digital input

configured to dry-running protection.

The use of a digital input requires an accessory, such

as:

• a Grundfos Liqtec® dry-running switch (for more

information on LiqTec, see Accessories on page 90)

• a pressure switch installed on the inlet side of the

pump

• a float switch installed on the inlet side of the pump.

The pump cannot restart as long as the digital input is

activated.

Temperature sensors 1 and 2

One or two Pt100 temperatures sensors may be

connected to the input terminals 17, 18, 19, and 20.

Fig. 24 Temperature sensor connections in the extended

functional module

Purpose and benefits

The temperature sensor inputs 1 and 2 provide these

benefits:

• The temperature sensor inputs can be used as input

to the limit exceeded functions 1 and 2.

• In combination with the bearing monitoring function,

the temperature sensors provide optimum

monitoring of the motor bearings.

• A bearing warning or a bearing alarm can be

indicated as the motor bearing temperature is

measured.

• Status readings of the measured temperatures are

available via Grundfos GO, PC Tool E-products and

a bus.

• The function has a built-in signal fault detection if

the temperature sensors fail or a conductor is

broken.

Applications

The temperature inputs can be used in all applications

where temperatures in the system or in the motor need

to be monitored.

Note: The temperature sensor inputs are available on

all MLE motors.

Description

The temperature sensor inputs enable several

functions.

• The temperature sensor inputs 1 and 2 can be used

as input to the limit exceeded functions 1 and 2. If a

limit is exceeded, this will be indicated. The

indication will be in the form of outputs (relay) or

alarms/warnings set or defined in the limit exceeded

functions 1 and 2.

• The temperature sensor inputs 1 and 2 can be set to

measure bearing temperature. The measured

values of temperature sensor 1 and 2 are used in

the calculation of relubrication intervals.

Additionally, the measured value can activate the

indication of a bearing warning or a bearing alarm.

In case of high bearing temperature, a warning or

an alarm can be logged and force the pump to stop.

Signal relays

Signal relays are used to give an output indication of

the current operational status of the MLE. The signal

relay is a potential free contact (also called a dry

contact). The output signals are typically transmitted to

external control systems.

Purpose and benefits

The signal relays offer these features:

• The signal relays can be remotely (via bus) or

internally controlled.

• The signal relays can be set to indicate several

types of operational status.

• A relay delay can be defined to avoid activating the

relay in case of periodic failures.

Applications

Signal relays can be used in all applications involving a

need to read out the operational status to e.g. a control

room or to a superior control system.

Description

The signal relays can be set with these three

parameters:

• relay control

• relay setup

• relay delay.

Relay control

The relay time is 0 seconds and the signal relay is

internally controlled.

The advanced relay control can only be set via PC Tool

E-products.

Relay control has these two setting options:

•Internally controlled

The relay is internally controlled by the variable

frequency drive software according to the setup of

the relay [Ready, Fault, Operation].

•Remotely controlled

The relay is controlled via commands from the

GENIbus.

Analog sensor inputs 1 and 2

The analog sensor inputs 1 and 2 are standardized

inputs for measuring all types of analog parameters.

Sensor input 1 is the only sensor input set for closed-

loop operation. The input will be used as the sensor

feedback input.

Sensor input 2 is referred to as the secondary sensor.

Fig. 27 Sensor inputs 1 and 2 connections

Purpose and benefits

The analog sensor inputs 1 and 2 provide these

benefits:

• Sensor input 1 can be feedback input for the built-in

PI controller.

• It is possible to monitor secondary parameters in

the process, e.g. flow rate or liquid temperature.

• The secondary sensor can be set as a redundant

sensor.

• The sensors can give input to the limit exceeded

functions 1 and 2.

• Status readings of the inputs are available via

Grundfos GO and PC Tool E-products.

Applications

Analog sensor inputs 1 and 2 can be used in

applications with a need for monitoring essential

parameters.

Description

The analog sensors 1 and 2 enable several functions.

• When the secondary sensor is set as an input to the

limit exceeded functions 1 and 2, defined outputs or

warnings or alarms can be given when system

parameters are outside defined system limits.

• Connecting a flow sensor.

When sensor input 2 is set with a flow sensor, the

measured value can be used as input to the

proportional-pressure function. The flow rate

displayed in Grundfos GO will be the measured flow

rate instead of the estimated flow rate.

The flow rate measurement can also be used in the

low-flow stop function to detect low flow instead of

estimating the flow rate by lowering the speed of the

pump.

• Sensor reading via Grundfos GO and PC Tool E-

products.

When sensors are set, the user can get a status

reading via Grundfos GO and PC Tool E-products.

Analog output

Analog output

The analog output (0-10 mA) can be set via PC Tool E-

products to one of these indications:

• feedback value

• speed

• frequency

• motor current

• external setpoint input

• limit exceeded.

The analog output is default set to not active.

Feedback value

The output signal is a function of the actual feedback

sensor.

Speed

The output signal is a function of the actual pump

speed.

Frequency

The output signal is a function of the actual frequency.

Motor current

The output signal is a function of the actual motor

current.

External setpoint input

The output signal is a function of the external setpoint

input.

Limit exceeded

The output signal indicates whether the limit is

exceeded:

• Minimum output = limit is not exceeded.

• Maximum output = limit is exceeded.

Limit exceeded 1 and 2

Limit exceeded is a monitoring function monitoring one

or two values or inputs. The function enables different

inputs to activate various outputs and alarms/

warnings when the signal input has exceeded pre-

determined limits.

Fig. 28 Example of a limit exceeded sequence

Purpose and benefits

The purpose of this function is to monitor parameters

which are central for the application. This will enable

the controller to react to possible, abnormal operating

conditions. This makes the E-pump a more important

and integrated part of a system, and it can thus replace

other existing monitoring units.

The liquid temperature can be monitored, and thus the

E-pump can ensure that the system temperature does

not exceed a maximum permissible level.

The minimum inlet pressure can be monitored, and

thus the E-pump can prevent damage caused by a

cavitation or dry run.

Applications

The limit exceeded function is typically used for

monitoring secondary parameters in the systems.

Description

The figures below show two examples of setpoint

monitoring by means of the limit exceeded function.

Fig. 29 Limit exceeded sequence with the limit type "max.

limit", for example monitoring of bearing

temperature

Fig. 30 Limit exceeded sequence with the limit type "min.

limit"

When the limit is exceeded, the signal input crosses

the limit as an increasing or decreasing value, and the

function can be set to cover both situations.

Pump operating at power limit

When a pump is operating at the power limit, the MLE

motor will deliver an output corresponding to the

maximum load stated on the nameplate. The maximum

load will never be exceeded. See fig. 31.

Fig. 31 Curves of a standard E-pump and a pump

operating at power limit

Purpose and benefits

When using a standard pump at a low flow rate, the

power consumption will drop and the motor will have

excess power available.

By setting the CRE pump to operate at a higher speed,

the excess power can be used to provide a higher

pressure. The power limit function will make sure that

the motor load never exceeds its maximum by

decreasing the speed until the motor is at its power

limit.

In cases where an undersized motor is used with

standard speed, the power limit function will still

reduce the speed and protect the motor against

overload at a high flow rate. The solution offers the

following benefits:

• reduced motor size

• reduced pump size.

Figure 32 shows that a pump operating at low flow

rates and relatively high pressures (1) can be fitted

with an undersize motor with a rated power that

matches this operating range. At higher flow rates and

relatively lower pressures (2), the motor will reduce its

speed when the power limit is exceeded and follow a

steeper curve corresponding to the power available.

Fig. 32 Standard performance curve compared to a curve

for a pump fitted with an undersize MLE motor.

The MLE motor can be set to a higher speed than a

standard motor, enabling the pump to deliver more

pressure. The pump will operate at this higher speed

until the pump reaches the flow rate where the motor is

loaded to its full rated power. If the flow rate is

increased further, the motor will reduce its speed so as

not to exceed its rated power.

Using this function can, in some instances, enable the

use of a smaller pump to reach the desired duty point

compared to a pump running with standard maximum

speed. See fig. 33.

Fig. 33 Standard performance curve (60 Hz) compared to

a performance curve for a pump running at

maximum speed.

Applications

The power limit function is primarily used in

applications where the motor size is dimensioned to be

as small as possible to reduce size or cost. It is also

used in applications demanding a high maximum

speed to achieve a high pressure at a low flow rate. In

both cases, the motor is protected by the power limit

function at a higher flow rate where a lower speed is

needed to prevent the motor from overloading.

Examples of applications:

• Washing and cleaning

• Boiler feed.

Setup

The power limit is always active in CRE pumps to

protect the motor against overload. Pumps with

undersize motor and pumps with higher maximum

speed are available as factory-configured products.

Note: Running the pump at over-synchronous speed

will affect the NPSH value, thus requiring a sufficient

inlet pressure to avoid cavitation.

The sound pressure level emitted from the pump and

motor may increase at higher speeds.

Furthermore, the differential pressure over the

chambers must be taken into consideration.

Stabilizing unstable pump curves

When the pump curve has a shape where it intersects

the system curve in two points (A and B) with identical

pressure but at different flow rates, the pump curve is

defined as unstable. See fig. 34. This is especially

problematic in systems with a flat system characteristic

as it prevents the pump from being controlled to a flow

rate which is lower than the flow rate at point B.

The E-motor can stabilize an unstable pump curve in

the low-flow area by changing to a higher speed.

Figure 35 illustrates how the pump curve is

straightened out in this area. As the flow rate

increases, the E-motor gradually reduces the speed to

normal speed and the pump performance will follow

the standard pump curve.

Fig. 35 Pump curve with a stabilized operating range

Purpose and benefits

The purpose of stabilizing an unstable pump is to

enable normal control throughout the entire operating

range. Thus fully stable operation is achieved, even in

the low-flow range. This enables the use of modern

high-efficiency pumps in applications where this would

otherwise not be possible.

Applications

As mentioned, unstable operation may occur in

applications with a high counter pressure and a flat

system characteristic.

Examples of applications:

• pumping of water to a water tower

• boiler feed.

Note: The sound pressure level emitted from the pump

and motor may increase at higher speeds.

Setup

This function is available in factory-configured

products.

5. Application examples of differential pressure in a

circulation system

Circulation systems (closed systems) are well-suited

for speed-controlled pump solutions.

It is an advantage that circulation systems with

variable system characteristic are fitted with a

differential-pressure-controlled circulator pump. See

fig. 36.

Fig. 36 Constant differential-pressure control

Figure 36 shows a heating system consisting of a heat

exchanger where the circulated water is heated and

delivered to three radiators by a speed-controlled

pump. A control valve is connected in series at each

radiator to control the flow rate according to the heat

requirement.

The pump is controlled according to a constant

differential pressure measured across the pump. This

means that the pump system offers constant

differential pressure in the Q range of 0 to Qmax.,

represented by the horizontal line in fig. 36.

Constant differential pressure

The differential pressure of the pump is kept constant,

independently of the flow rate. See fig. 37.

Fig. 37 Constant differential pressure, pump

The pump is controlled according to a constant

differential pressure measured across the pump. This

means that the pump system offers constant

differential pressure in the Q-range of 0 to Qmax.,

represented by the horizontal line in the QH diagram.

Proportional differential pressure

The differential pressure of the pump is reduced at

falling flow rate and increased at rising flow rate. See

fig. 38.

Fig. 38 Proportional differential pressure

The pump is controlled according to a differential

pressure measured across the pump. This means that

the pump system offers a proportional differential

pressure in the Q-range of 0 to Qmax., represented by

Setting via PC Tool.

The proportional differential pressure can be selected

with one of these flow dependencies:

• linear (setting via PC Tool).

• parabolic (setting via PC Tool).

When the flow dependency is selected as parabolic,

the differential pressure of the pump will be reduced

with a parabolic curve at falling flow rate and increased

at rising flow rate. See fig. 39.

Fig. 39 Proportional differential pressure, parabolic curve

The pump is controlled according to a differential

pressure measured across the pump. This means that

the pump system offers a flow-compensated

Constant differential pressure

The setpoint range is between 12.5 % to 100 % of

maximum head.

Proportional differential pressure

The setpoint range is between 25 % to 90 % of

To compensate for this excessive system pressure, the

1) In August 2003, the NEMA version pump code was discontinued

for all material numbers created by Grundfos manufacturing

companies in North America. The NEMA version pump code will

still remain in effect for existing material numbers. NEMA version

pumps built in North America after this change will have either an A

or U as the pump version code depending on the date the material

number was created.

Maximum inlet pressure

The following table shows the maximum permissible

inlet pressure. However, the current inlet pressure +

the pressure against a closed valve must always be

lower than the maximum permissible operating

pressure.

If the maximum permissible operating pressure is

exceeded, the conical bearing in the motor may be

damaged and the life of the shaft seal reduced.

Examples of operating and inlet pressures

The values for operating and inlet pressures shown in

the table above must not be considered individually but

must always be compared. See the following

examples:

Example 1:

Pump: CRE 3-10 A-A-A

Maximum operating pressure:232 psi

Maximum inlet pressure: 145 psi

Outlet pressure against a closed valve: 139.2 psi, see

page 48.

This pump must not start at an inlet pressure of 145

psi, but at an inlet pressure of 232.0 - 139.2 = 92.8 psi.

Example 2:

Pump: CRE 10-2 A-GJ-A

Maximum operating pressure: 232 psi

Maximum inlet pressure: 116 psi

Outlet pressure against a closed valve: 42 psi (97 ft),

see page 56.

This pump may start at an inlet pressure of 116 psi, as

the outlet pressure is only 42 psi, which results in an

operating pressure of 116 + 42 = 158 psi. On the

contrary, the maximum operating pressure of this

pump is limited to 158 psi, as a higher operating

pressure will require an inlet pressure of more than

116 psi.

In case the inlet or operating pressure exceeds the

pressure permitted, see Lists of variants on request on

page 107.

Selection and sizing

9. Selection and sizing

Selection of pump

Selection of pump must be based on the following

information

• the duty point of the pump, see section 1 below

• sizing data such as pressure loss as a result of

height differences, friction loss in the pipes, pump

efficiency etc., see section 2 below

• pump materials, see section 3 below

• pump connections, see section 4 below

• The shaft seal, see section 5 below.

1. Duty point of the pump

From a duty point it is possible to select a pump on the

basis of the curve charts in the section Minimum flow

rate on page 43.

Fig. 46 Example of a curve chart

2. Sizing data

When sizing a pump the following information must be

taken into account:

• required flow rate and pressure at the point of use

• pressure loss as a result of height differences (Hgeo)

• friction loss in the pipes (Hf)

It may be necessary to account for pressure loss in

connection with long pipes, bends or valves, etc.

• best efficiency at the estimated duty point

• NPSH value

For calculation of the NPSH value, see Minimum

inlet pressure - NPSHA on page 42.

Fig. 47 Sizing data

Pump efficiency

Before determining the point of best efficiency, the

operating pattern of the pump needs to be identified. If

the pump is expected to operate at the same duty

point, then select a CRE pump which is operating at a

duty point corresponding to the best efficiency of the

pump.

Fig. 48 Example of a CR pump's duty point

As the pump is sized on the basis of the highest

possible flow rate, it is important to always have the

duty point to the right of the best efficiency point (see

fig. 49, range with check mark). This must be

considered in order to keep efficiency high when the

flow rate drops.

Normally, E-pumps are used in applications

characterized by a variable flow rate. Consequently, it

is not possible to select a pump that is constantly

operating at its best efficiency.

In order to achieve optimum operating economy, select

the pump on the basis of the following criteria:

• The maximum required duty point must be as close

as possible to the QH curve of the pump.

• The required duty point must be positioned so that

P2 is close to the maximum point of the 100 %

curve.

Between the minimum and maximum performance

curve E-pumps have an infinite number of performance

curves each representing a specific speed. Therefore

it may not be possible to select a duty point close to

the 100 % curve.

Fig. 50 Minimum and maximum performance curves

In situations where it is not possible to select a duty

point close to the 100 % curve the affinity equations to

the right can be used. The head (H), the flow rate (Q)

and the input power (P) are all the appropriate

variables for determining the motor speed (n). See fig.

51.

Note:

The approximated formulas apply on condition that the

system characteristic remains unchanged for nn and

nx and that it is based on the formula H = k x Q2,

where k is a constant.

The power equation implies that the pump efficiency is

unchanged at the two speeds. In practice this is not

quite correct.

Finally, it is worth noting that the efficiencies of the

frequency converter and the motor must be taken into

account if a precise calculation of the power saving

resulting from a reduction of the pump speed is

wanted.

3. Material

Select the material variant, CRE, CRIE, CRNE, on the

basis of the liquid to be pumped. The product range

covers three basic types.

• The CRE, CRIE pump types are suitable for clean,

non-aggressive liquids such as potable water, oils,

etc.

• The CRNE pump type is suitable for industrial

liquids and acids, see List of pumped liquids on

page 87 or contact Grundfos.

For saline or chloride-containing liquids such as sea

water, CRTE pumps of titanium are available.

4. Pump connection

Selection of pump connection depends on the rated

pressure and the pipes. To meet any requirement, the

CRE, CRIE and CRNE pumps offer a wide range of

flexible connections such as:

• oval flange (NPT), fig. 53

• ANSI flange, fig. 53

• PJE coupling, fig. 53

• clamp coupling

• union (NPT[M])

• other connections on request.

5. Shaft seal

As standard, the CRE range is fitted with a Grundfos

shaft seal of the cartridge type which suitable for the

most common applications. See fig. 54.

The following three key parameters must be taken into

account, when selecting the shaft seal:

• type of pumped liquid

• liquid temperature

• maximum pressure.

Grundfos offers a wide range of shaft seal variants to

meet specific demands. See List of pumped liquids on

page 87.

6. Inlet pressure and operating pressure

Do not exceed the limit values stated on page 38 and

page 36 as regards these pressures:

• maximum inlet pressure and

• maximum operating pressure.

Minimum inlet pressure - NPSHA

We recommend that you calculate the inlet pressure

"H" in these situations:

• The liquid temperature is high.

• The flow rate is significantly higher than the rated

flow rate.

• Water is drawn from depths.

• Water is drawn through long pipes.

• Inlet conditions are poor.

To avoid cavitation, make sure that there is a minimum

pressure on the inlet side of the pump. The maximum

suction lift "H" in feet can be calculated as follows:

If the "H" calculated is positive, the pump can operate

at a suction lift of maximum "H" feet.

If the "H" calculated is negative, an inlet pressure of

minimum "H" feet is required.

Fig. 55 Minimum inlet pressure - NPSHR

Note: In order to avoid cavitation, never select a pump

whose duty point lies too far to the right on the NPSHR

curve.

Always check the NPSHR value of the pump at the

highest possible flow rate.

In case a lower NPSHR value is required, see Lists of

variants on request on page 107.

H=p

b - NPSHR - Hf - Hv - Hs.

Pb= Barometric pressure in feet absolute. (The

barometric pressure can be set to 33.9 feet

at sea level. In closed systems, pb indicates

system pressure in feet.)

NPSHR = Net Positive Suction Head Required in feet.

(To be read from the NPSHR curve at the

highest flow rate the pump will be

delivering).

Hf= Friction loss in the inlet pipe in feet. (At the

highest flow rate the pump will be

delivering.)

Hv= Vapor pressure in feet. (To be read from the

vapor pressure scale. "Hv" depends on the

liquid temperature "Tm").

Hs= Safety margin = minimum 2.0 feet.

Guidelines to the performance curves

The guidelines below apply to the curves shown on the

following pages:

1. The motors used for the measurements are

standard motors (ODP, TEFC or MLE).

2. Measurements have been made with airless water

at a temperature of 68 °F (20 °C).

3. The curves apply to a kinematic viscosity of  = 1

mm2/s (1 cSt).

4. Due to the risk of overheating, the pumps must not

be used at a flow rate below the minimum flow rate.

5. The QH curves apply to actual speed with the motor

types mentioned at 60 Hz.

The curve below shows the minimum flow rate as a

percentage of the rated flow rate in relation to the

liquid temperature. The dotted line shows a CRE pump

fitted with an air-cooled top assembly.

Pumped liquids

CRE, CRIE, CRNE 12

12. Pumped liquids

Thin, non-explosive liquids, not containing solid

particles or fibers. The liquid must not chemically

attack the pump materials. When pumping liquids with

a density and/or viscosity higher than that of water,

oversized motors must be used.

Whether a pump is suitable for a particular liquid

depends on a number of factors of which the most

important are the chloride content, pH value,

temperature and content of chemicals, oils, etc.

Please note that aggressive liquids, such as sea water

and some acids, may attack or dissolve the protective

oxide film of the stainless steel and thus cause

corrosion. The CRE, CRIE, CRNE pump types are

suitable for the following liquids:

CRE, CRIE

• Non-corrosive liquids.

For liquid transfer, circulation and pressure boosting of

cold or hot clean water.

CRNE

Industrial liquids in systems where all parts in contact

with the liquid must be made of high-grade stainless

steel.

CRTE

• Saline liquids

• hypochlorites

•acids.

For saline or chloride-containing liquids, such as sea

water or oxidizing agents such as hypochlorites, CRTE

pumps of titanium are available. See separate product

guide on CRT, CRTE.

List of pumped liquids

A number of typical liquids are listed on the following

pages.

Other pump versions may be applicable, but those

stated in the list are considered to be the best choices.

The table is intended as a general guide only, and

cannot replace actual testing of the pumped liquids

and pump materials under specific working conditions.

The list should, however, be applied with some caution

as factors such as the following may affect the

chemical resistance of a specific pump version:

• concentration of the pumped liquid

• liquid temperature

• pressure.

Safety precautions must be made when pumping

dangerous liquids.

Notes

DOften with additives.

EDensity and/or viscosity differ from that of water. Allow for

this when calculating motor output and pump

performance.

FPump selection depends on many factors. Contact

Grundfos.

HRisk of crystallization/precipitation in shaft seal

1The pumped liquid highly flammable.

2The pumped liquid is combustible.

LiqTec

Description

LiqTec has the following features:

• Protection of the pump against dry-running.

• Protection of the pump against too high liquid

temperature (+266 °F ± 9 °F (130 °C ± 5 °C)).

• A fail-safe design. If the sensor, sensor cable,

electronic unit or power supply fails, the pump stops

immediately.

•LiqTec is not to be used with the MGFlex motor.

Mounting the LiqTec sensor

LiqTec can be fitted to a DIN rail to be incorporated in a

control cabinet.

Electrical connection

Example of electrical connection, see page 97.

Calibration of sensor and controller

Follow the procedure on the next page.

Functions

Fig. 58 LiqTec functions

1. Connection for dry-running sensor

2. Connection for external restarting

3. Motor PTC

Green light indicates OK or short-circuited

terminals.

Red light indicates too high motor temperature. The

alarm relay is activated.

4. Connection for PTC sensor

This input is not used in connection with E-pumps

as the variable frequency drive protects the motor

against overload.

5. Sensor indicator light

Red light indicates defective sensor or cable. The

alarm relay is activated.

6. Deactivation of the dry-running monitoring

function

Press the button to deactivate the dry-running

monitoring function. Red flashing light. The PTC

monitoring function is still active. Press [Restart] to

reactivate the dry-running monitoring function.

7. High liquid temperature indicator light

Red light indicates too high liquid temperature

(+266 °F ± 9 °F (130 °C ± 5 °C)). The alarm relay is

activated.

8. Supply voltage

200-240 VAC, 50/60 Hz and 80-130 VAC 50/60 Hz.

9. Dry-running indicator light

Green light indicates OK (liquid in pump).

Red light indicates dry running (no liquid in pump).

The alarm relay is activated.

10.Alarm/Run relay output

Potential-free changeover contact.

Maximum contact load: 250 V, 1 A, AC (inductive

load).

11.Auto/Man

Changeover between automatic and manual

restarting. The default setting is "Man".

Changeover is carried out by means of a small

screwdriver. When "Auto" has been selected, the

alarm indication will automatically be reset 10 to 20

seconds after detection of liquid.

12.Restart

Note:

LiqTec is not be connected to the PTC sensor.

Assemble a jumper wire between the two terminals at

pos. 4 on the controller.

The MLE motor software provides protection against

high motor temperature.

LiqTec is designed for DIN rail mounting in a control

cabinet.

Step Action Result

1Connect the sensor to pos. 1 on the controller and connect the power supply to pos.

8 on the controller. See page 97.

2

Submerge the sensor into the pumped liquid. The pumped liquid and the air

temperature are to be +70 °F.

Note: It is important that the pumped liquid is stagnant as the calibration will be

misleading if the sensor is cooled by flowing water.

3Press the buttons at pos. 6 and pos. 12 on the controller for approximately 20

seconds. All red indicator lights (except pos. 7) start flashing.

4When the green indicator lights at pos. 3 and pos. 9 on the controller are constantly

on, release the buttons at pos. 6 and pos. 12. The calibration is completed.

Connections and other variants

Shaft seals

Pumps

Variant Description

Explosion proof

motors

For operation in hazardous atmospheres,

explosion-proof or dust-ignition-proof

motors may be required.

Motors with anti-

condensation heating

unit

For operation in humid environments

motors with built-in anti-condensation

heating may be required.

Premium efficient

motors Grundfos offers motors from 1 to 100 HP

with a Premium efficiency class.

Different motor brand

If technically possible, Grundfos can fit the

pump with a motor of a brand other than the

standard. This will normally increase the

time of delivery. Alternatively, the pump can

be supplied without a motor (motor thrust

rating must be checked).

Oversized motor

Ambient temperatures above 104 °F (40

°C) or installation at altitudes of more than

3280 ft above sea level require the use of

an oversized motor (i.e. derating).

4-pole motors Grundfos offers standard motors fitted with

4-poles.

Variant Description

Pipe connections

In addition to the wide range of standard

flange connections, a 232 psi DIN standard

clamping flange is available.

Customized flanges are available

according to specifications.

TriClamp connections TriClamp connections are of a hygienic

design with a sanitary coupling for use in

the pharmaceutical and food industry.

Electropolished

pumps

Electropolishing substantially reduces the

risk of corrosion of the materials.

Electropolishing is used in the

pharmaceutical/food industry.

Variant Description

Shaft seal with

FFKM O-ring

material

We recommend shaft seals with FFKM or FXM O-

ring material for applications where the pumped

liquid may damage the standard O-ring material.

Seal with flush,

quench seal Recommended for applications involving

crystallizing, hardening or sticky liquids.

Cool-Top®

shaft seal

system

Recommended for applications involving extremely

high temperatures.

No conventional mechanical shaft seal can

withstand liquid temperatures of up to 356 °F for

any length of time.

For that type of application, we recommend

Grundfos' unique air-cooled shaft seal system.

In order to ensure a low liquid temperature around

the standard shaft seal, the pump is fitted with a

special air-cooled shaft seal chamber.

No separate cooling is required.

Double shaft

seal with

pressure

chamber

Recommended for applications involving poisonous

or explosive liquids.

Protects the surrounding environment and the

people working in the vicinity of the pump.

Consists of two seals mounted in a "back-to-back"

arrangement inside a separate pressure seal

chamber. As the pressure in the chamber is higher

than the pump pressure, leakage is prevented. A

dosing pump or a special pressure-intensifier

generates the seal chamber pressure.

CRN MAGdrive

Magnetically driven pumps for industrial

applications.

Key applications are industrial processes involving

the handling of aggressive, environmental,

dangerous or volatile liquids, e.g. organic

compounds, solvents, etc.

Variant Description

Horizontally

mounted pump

For safety or height reasons, certain

applications, for instance on ships, require the

pump to be mounted in the horizontal position.

For easy installation the pump is equipped

with brackets that support motor and pump.

Low-temperature

pump to -4 °F

Exposed to temperatures down to -40 °F (-40

°C) coolant pumps may require neck-rings

with a different diameter in order to prevent

impeller drag.

High-speed pump

up to 681 psi

For high-pressure applications, a unique pump

capable of generating up to 681 psi (47 bar)

pressure is available.

The pump is equipped with a high-speed

motor, type MLE. The direction of rotation is

the opposite of that of standard pumps, and

the chamber stack is turned upside-down, as a

result of which the pumped liquid flows in the

opposite direction.

High-pressure

pump up to 696 psi

For high-pressure applications, a unique

double pump system capable of generating up

to 696 psi (48 bar) pressure is available.

Low-NPSH pump

(improved suction)

Recommended for boiler-feed applications

where cavitation may occur due to poor inlet

conditions.

Belt-driven pumps Belt-driven pumps designed to operate in

places with limited space or where no

electrical power is available.

Pumps for

pharmaceutical and

biotechnological

applications

CRN, CRNE pumps designed for applications

requiring the sterilization and CIP capability of

pipes, valves and pumps. (CIP = Cleaning-In-

Place).
