Introduction

CRE, CRIE, CRNE pumps

TM02 7397 3403

This data booklet deals with CR, CRI and CRN as well
as CRE, CRIE and CRNE pumps.

GR5381

Fig. 2 CRE, CRIE and CRNE pumps

Fig. 1 CR, CRI and CRN pumps

CRE, CRIE and CRNE pumps are built on the basis of
CR, CRI, CRN pumps.
CRE, CRIE and CRNE pumps belong to the so-called
E-pump family. CRE, CRIE and CRNE pumps are
referred to as E-pumps.

CR, CRI and CRN pumps are vertical multistage centrifugal pumps. The in-line design enables the pump to be
installed in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal
plane and have the same pipe dimensions. This design
provides a more compact pump design and pipework.

The difference between the CR and the CRE pump
range is the motor. CRE, CRIE and CRNE pumps are
fitted with an E-motor, i.e. a motor with built-in frequency control.

Grundfos CR pumps come with various pump sizes and
various numbers of stages to provide the flow and the
pressure required.

Frequency control enables continuously variable control of motor speed, which makes it possible to set the
pump to operation at any duty point. The aim of continuously variable control of the motor speed is to adjust
the performance to a given requirement.

CR pumps are suitable for a variety of applications from
pumping of potable water to pumping of chemicals. The
pumps are therefore used in a wide diversity of pumping systems where the performance and material of the
pump meet specific demands.
The CR pumps consist of two main components: The
motor and the pump unit. The motor of CR pumps is a
Grundfos motor designed to EN standards.
The pump unit consists of optimised hydraulics, various
types of connections, an outer sleeve, a pump head
and various other parts.
CR pumps are available in various material versions
according to the pumped liquid.

The motor of the CRE pump is a Grundfos MGE or
MMGE motor designed to EN standards.

CRE, CRIE and CRNE pumps are available with an
integrated pressure sensor connected to the frequency
control.
The pump materials are the same as those of the CR,
CRI and CRN pump range.
Selecting a CRE pump
Select a CRE pump if:
• controlled operation is required, i.e. consumption
fluctuates,
• constant pressure is required,
• communication with the pump is required.
Adaptation of performance through frequency-controlled speed control offers obvious advantages:
• Energy savings.
• Increased comfort.
• Control and monitoring of the pump performance.

Motor protection

Ambient temperature

MG and Siemens motors
Single-phase Grundfos motors have a built-in thermal
overload switch (IEC 34-11: TP 211).

0.37-0.75 kW motors (EFF 2, MG):

Max. +40°C.

1.1-11 kW motors (EFF 1, MG):

Max. +60°C.

Three-phase motors must be connected to a motor
starter in accordance with local regulations.
Three-phase Grundfos motors from 3 kW and upwards
have a built-in thermistor (PTC) according to DIN
44 082 (IEC 34-11: TP 211).
MGE motors
CRE, CRIE, CRNE pumps require no external motor
protection. The MGE motor incorporates thermal protection against slow overloading and blocking (IEC 3411: TP 211).

15-45 kW motors (EFF 1, Siemens): Max. +55°C.
If the ambient temperature exceeds above maximum
values or if the motor is located 1000 metres above sea
level, the motor output (P2) must be reduced due to the
low density and consequently low cooling effect of the
air. 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 the pump should be equipped with a
larger motor. If in doubt, contact Grundfos.

Control of E-pumps
Examples of E-pump applications
CRE, CRIE and CRNE pumps are the ideal solution in
a number of applications characterized by a need for
variable flow at constant pressure. The pumps are
suited for water supply systems and pressure boosting,
but also industrial applications.
Depending on the nature of the application, the pumps
offer energy-savings, increased comfort and improved
processing.
E-pumps in the service of industry
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.
Below is mentioned some of the applications in which
E-pumps are often used.

CR, CRI, CRN, CRE, CRIE, CRNE

Constant flow
• Steam boiler 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,

Constant pressure
• Water supply,

• Degreasing systems,

• Washing and cleaning systems,

Example: In the petrochemical industry, E-pumps with
pressure sensor are used as dosing pumps. The Epumps helps to ensure that the correct mixture ratio is
achieved when more liquids are combined.

• 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 piping network. 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 a preset setpoint.
Constant temperature
• Air-conditioning systems at industrial plants,
• Industrial cooling systems,
• Industrial freezing systems,
• Casting and moulding 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.

• Bleaching systems, etc.

E-pumps functioning as dosing pumps improves
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.
Constant pressure
• Water supply in high-rise buildings i.e. office buildings, hotels, etc.
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,
• Building cooling systems, etc.
Example: E-pumps are an excellent solution in buildings where constant temperature is essential. E-pumps
keep the temperature constant in air-conditioned highrise glass buildings, irrespective of the seasonal fluctuations of the out-door temperature, and various heat
impacts inside the building.

Control of E-pumps

CR, CRI, CRN, CRE, CRIE, CRNE

Control options of E-pumps
Communication with CRE, CRIE, CRNE pumps is possible by means of

Remote control

• a central management system,

The operator communicates with the E-pump by pointing the IR-signal transmitter at the control panel of the
E-pump terminal box.

• remote control (Grundfos R100) or
• a control panel.

The R100 remote control produced by Grundfos is
available as an accessory.

TM00 4498 2802

The purpose of controlling an E-pump is to monitor and
control the pressure, temperature, flow and liquid level
of the system.

Central management system
Communication with the E-pump is possible even
though the operator is not present near the E-pump.
Communication is enabled by having connected the Epump to a central management system allowing the
operator to monitor and change control modes and setpoint settings of the E-pump.

Fig. 7 R100 remote control

On the R100 display it is possible to monitor and
change control modes and settings of the E-pump.

Control of E-pumps

CR, CRI, CRN, CRE, CRIE, CRNE

Control modes for E-pumps
Grundfos offers CRE, CRIE and CRNE pumps in two
different variants:

In constant-curve mode, the pump is not controlled. It
can be set to pump according to a preset pump characteristic within the range from min. curve to max. curve,
see figure below.

• CRE, CRIE and CRNE with integrated pressure
sensor

H

• CRE, CRIE and CRNE without sensor.

Max.

CRE, CRIE, CRNE with integrated
pressure sensor
CRE, CRIE and CRNE pumps with integrated pressure
sensor are suitable for applications where you want to
control the pressure after the pump, irrespective of the
flow. For further information, see the section "Examples
of E-pump applications" page 9.
Signals of pressure changes in the piping 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 piping system.

CRE, CRIE and CRNE without sensor
CRE, CRIE and CRNE pumps without sensor are suitable for applications where
• uncontrolled operation is required
• you want to fit another sensor later in order to control the flow, temperature, differential temperature,
liquid level, pH value, etc at some arbitrary point in
the system.
CRE, CRIE and CRNE pumps without sensor can be
set to:
• controlled-operation mode or
• uncontrolled-operation mode (factory-setting).

This pump is not allowed to start at an inlet pressure of

Example 2:
The following pump type has been selected:
CR 10-2 A-A-A

This pump is allowed to start at an inlet pressure of 8.0
bar, as the discharge pressure against a closed valve is
only 2.0 bar, which results in an operating pressure of
8.0 + 2.0 = 10.0 bar. On the contrary, the max. operating pressure of this pump is limited to 16.0 bar, as a
higher operating pressure will require an inlet pressure
of more than 8.0 bar.

Selection and sizing

CR, CRI, CRN, CRE, CRIE, CRNE

Selection of pumps

Pump efficiency
Before determining the best efficiency point, the operation pattern of the pump needs to be identified.

Selection of pumps should be based on:
• The duty point of the pump (see section 1)
• Dimensional data such as pressure loss as a result
of height differences, friction loss in the pipework,
pump efficiency etc. (see section 2)
• Pump materials (see section 3)
• Pump connections (see section 4)

Is the pump expected to operate at the same duty point,
then select a CR pump which is operating at a duty
point corresponding with the best efficiency of the
pump.

Normally, E-pumps are used in applications characterized by a variable flow. Consequently, it is not possible
to select a pump that is constantly operating at optimum
efficiency.

In situations where it is not possible to select a duty
point close to the 100% curve the below affinity equations can be used. The head (H), the flow (Q) and the
input power (P) are all the appropriate variables for the
motor speed (n).
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.

WinCAPS and WebCAPS
WinCAPS and WebCAPS are both selection programmes offered by Grundfos.
The two programmes make it possible to calculate an
E-pump’s specific duty point and energy consumption.
By entering the dimensional data of the pump, WinCAPS and WebCAPS can calculate the exact duty point
and energy comsumption. For further information see
page 80 and page 81.

3. Pump material
The material variant (CR(E), CRI(E), CRN(E)) should
be selected based of the liquid to be pumped. The product range covers the following three basic types.

TM01 2100 1198

• The CR(E), CRI(E) pump types are suitable for
clean, non-aggressive liquids such as potable water, oils, etc.
• The CRN(E) pump type is suitable for industrial liquids and acids, see” "List of pumped liquids" on
page 68 or contact Grundfos.
For saline or chloride-containing liquids such as sea
water, CRT(E) pumps of titanium are available.

Fig. 21 CR pump

4. Pump connections
Selection of pump connection depends on the rated
pressure and pipework. To meet any requirement the
CR(E), CRI(E) and CRN(E) pumps offer a wide range
of flexible connections such as:

F (DIN)

P (PJE)
A (oval)
TM02 1201 0601

• Oval flange (BSP)
• DIN flange
• PJE coupling
• Clamp coupling
• Union (+GF+)

Fig. 22 Pump connections

• Other connections on request.
5. Shaft seal
As standard, the CR(E) range is fitted with a Grundfos
shaft seal (cartridge type) suitable for the most common
applications.
TM02 0538 4800

The following key parameters must be taken into
account, when selecting the shaft seal:
• Type of pumped liquid
• liquid temperature and
• maximum pressure.
Grundfos offers a wide range of shaft seal variants to
meet specific demands see "List of pumped liquids" on
page 68.

Fig. 23 Shaft seal (cartridge type)

Inlet pressure and operating pressure

Guidelines to performance curves

• Tolerances to ISO 9906, Annex A, if indicated.
• The motors used for the measurements are standard Grundfos motors (MG or MGE).
• Measurements have been made with airless water
at a temperature of 20°C.
• The curves apply to a kinematic viscosity of
2
υ = 1 mm /s (1 cSt).
• Due to the risk of overheating, the pumps should not
be used at a flow below the minimum flow rate.
• The QH curves apply to a rated motor speed of
2900 min-1. All curves are based on current motor
speeds.

The curve below shows the minimum flow rate as a percentage of the nominal flow rate in relation to the liquid
temperature. The dotted line shows a CR pump fitted
with an air-cooled top assembly.

Pumped liquids

CR, CRI, CRN, CRE, CRIE, CRNE

Pumped liquids

List of pumped liquids

Thin, non-explosive liquids, not containing solid particles or fibres. The liquid must not chemically attack the
pump materials.

A number of typical liquids are listed below.
Other pump versions may be applicable, but those
stated in the list are considered to be the best choices.

When pumping liquids with a density and/or viscosity
higher than that of water, oversized motors must be
used, if required.

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.

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.

The list should, however, be applied with some caution
as factors such as
• concentration of the pumped liquid,
• liquid temperature or

Please note that aggressive liquids (e.g. sea water and
some acids) may attack or dissolve the protective oxide
film of the stainless steel and thus cause corrosion.

• pressure.
may affect the chemical resistance of a specific pump
version.

The CR(E), CRI(E), CRN(E) pump types are suitable
for the following liquids:

Safety precautions must be made when pumping dangerous liquids.

CR(E), CRI(E)
• Non-corrosive liquids.

Notes
D

Often with additives.

E

Density and/or viscosity differ from that of water.
Allow for this when calculating motor output and pump
performance.

F

Pump selection depends on many factors.
Contact Grundfos.

In systems where all parts in contact with the liquid
must be made of high-grade stainless steel.

H

Risk of chrystallization/precipitation in shaft seal.

1

The pumped liquid highly inflammable.

2

The pumped liquid is combustible.

CRT(E)
• Saline liquids.

3

Insoluble in water.

4

Low self-ignition point.

For liquid transfer, circulation and pressure boosting of
cold or hot clean water.
CRN(E)
• Industrial liquids.

• Hypochlorites.
• Acids.
For saline or chloride-containing liquids such as sea
water or oxidizing agents such as hypochlorites,
CRT(E) pumps of titanium are available. See separate
data booklet on CRT(E).

CR, CRI, CRN, CRE, CRIE, CRNE

Pumps
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

Exposed to temperatures down to –40°C, coolant pumps may require neck-rings with a different diameter in order to prevent impeller drag.

High-speed pump
up to 47 bar

For high-pressure applications, Grundfos offers
a unique pump capable of generating up to 47
bar.
The pump is equipped with a high-speed motor, type MGE. 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.
For high-pressure applications,Grundfos offers
a unique double pump system capable of generating a pressure of up to 47 bar pressure.

Motors
Variant

Description

ATEX motor

For operation in hazardous atmospheres, explosion-proof or dust-ignition-proof motors may
be required.

High-pressure
pump up to 47 bar

Motor with anticondensation
heating unit

For operation in humid environments motors
with built-in anti-condensation heating unit may
be required.

Recommended for boiler-feed applications
Low-NPSH pump
where cavitation may occur due to poor inlet
(improved suction)
conditions.

Grundfos offers motors with built-in bimetallic
Motor with thermal thermal switches or temperature-controlled
protection
PTC sensors (thermistors) incorporated in the
motor windings.
Oversize motor
4-pole motor

Ambient temperatures above 40°C or installation at altitudes of more than 1000 metres
above sea level require the use of an oversize
motor (i.e. derating).

The bearing flange is suitable for applications
where the inlet pressure is higher than the
Pump with bearing maximum pressure recommended.
The bearing flange increases the life of motor
flange
bearings.
(Recommended for standard motors.)
Belt-driven pump

Belt-driven pumps designed to operate in
places with limited space or where no electrical
power is available.

Pump for pharmaceutical and biotechnological
applications

CRN(E) pumps designed for applications requiring the sterilization and CIP capability of
pipes, valves and pumps. (CIP = Cleaning-InPlace.)

Grundfos offers 4-pole standard motors.

Shaft seals
Variant

Description

Shaft seal with
FFKM O-ring
material

Shaft seals with FFKM or FXM O-ring material
are recommended for applications where the
pumped liquid may damage the standard Oring material.

Seal with flush,
quench seal

Recommended for applications involving crystallizing, hardening or sticky liquids.

Air-cooled shaft
seal system

Recommended for applications involving extremely high temperatures.
No conventional mechanical shaft seal can
withstand liquid temperatures of up to 180°C
for any length of time.
For such applications, Grundfos’ unique aircooled shaft seal system is recommended.
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 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-toback" 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.

CR MAGdrive

Magnetically driven pumps for industrial applications.
Key applications are industrial processes invoving the handling of aggressive, environmental, dangerous or volatile liquids, e.g. organic
compounds, solvents, etc.
