Introduction
This data booklet deals with CR, CRI and CRN as well
as CRE, CRIE and CRNE pumps.
Fig. 1 CR, CRI and CRN pumps
CR, CRI and CRN pumps are vertical multistage centri-
fugal pumps. The in-line design enables the pump to be
installed in a horizontal one-pipe system where the suc-
tion 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.
Grundfos CR pumps come with various pump sizes and
various numbers of stages to provide the flow and the
pressure required.
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 pump-
ing 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.
CRE, CRIE, CRNE pumps
Fig. 2 CRE, CRIE and CRNE 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.
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 fre-
quency control.
The motor of the CRE pump is a Grundfos MGE or
MMGE motor designed to EN standards.
Frequency control enables continuously variable con-
trol of motor speed, which makes it possible to set the
pump to operation at any duty point. The aim of contin-
uously variable control of the motor speed is to adjust
the performance to a given requirement.
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-control-
led speed control offers obvious advantages:
• Energy savings.
• Increased comfort.
• Control and monitoring of the pump performance.

Motor protection
MG and Siemens motors
Single-phase Grundfos motors have a built-in thermal
overload switch (IEC 34-11: TP 211).
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 pro-
tection against slow overloading and blocking (IEC 34-
11: TP 211).
Terminal box positions
As standard the terminal box is mounted on the suction
side of the pump.
Fig. 4 Terminal box positions
Ambient temperature
0.37-0.75 kW motors (EFF 2, MG): Max. +40°C.
1.1-11 kW motors (EFF 1, MG): Max. +60°C.
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.
Fig. 5 Relationship between motor output (P2) and am-
bient temperature
Viscosity
The pumping of liquids with densities or kinematic vis-
cosities higher than those of water will cause a consid-
erable 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 differ-
ent applications. Demands on pumps in terms of pump
performance and mode of operation make speed con-
trol a must in many applications.
Below is mentioned some of the applications in which
E-pumps are often used.
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 con-
stant 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 stabi-
lized 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 operat-
ing costs compared with pumps without a temperature
sensor.
An E-pump continuously adapts its performance to the
changing demands reflected in the differences in tem-
perature 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 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 con-
stant 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-effi-
cient 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 helps to ensure that the correct mixture ratio is
achieved when more liquids are combined.
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 build-
ings, 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 con-
sumption pattern and thus the pressure changes during
the day, the E-pump continuously adapts its perform-
ance 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 build-
ings where constant temperature is essential. E-pumps
keep the temperature constant in air-conditioned high-
rise glass buildings, irrespective of the seasonal fluctu-
ations 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 pos-
sible by means of
• a central management system,
• remote control (Grundfos R100) or
• a control panel.
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 E-
pump to a central management system allowing the
operator to monitor and change control modes and set-
point settings of the E-pump.
Fig. 6 Structure of a central management system
Remote control
The R100 remote control produced by Grundfos is
available as an accessory.
The operator communicates with the E-pump by point-
ing the IR-signal transmitter at the control panel of the
E-pump terminal box.
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 panel
The control panel of the E-pump terminal box makes it
possible to change the setpoint settings manually.

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:
• CRE, CRIE and CRNE with integrated pressure
sensor
• CRE, CRIE and CRNE without sensor.
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 per-
formance up or down to compensate for the pressure
difference between the actual and the desired pres-
sure. As this adjustment is a continuous process, a con-
stant pressure is maintained in the piping system.
Fig. 9 CRE, CRIE and CRNE pumps
A CRE, CRIE or CRNE pump with integrated pressure
sensor facilitates installation and commissioning.
CRE, CRIE and CRNE pumps with integrated pressure
sensor can be set to:
• constant-pressure mode (factory setting) or
• constant-curve mode.
In constant-pressure mode, the pump maintains a
preset pressure after the pump, irrespective of the flow,
see figure below.
Fig. 10 Constant pressure mode
In constant-curve mode, the pump is not controlled. It
can be set to pump according to a preset pump charac-
teristic within the range from min. curve to max. curve,
see figure below.
Fig. 11 Constant curve mode
CRE, CRIE and CRNE without sensor
CRE, CRIE and CRNE pumps without sensor are suit-
able for applications where
• uncontrolled operation is required
• you want to fit another sensor later in order to con-
trol 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).
In controlled-operation mode, the pump adjusts its
performance to the desired setpoint, see figure below.
Fig. 12 Constant flow mode
In uncontrolled-operation mode, the pump operates
according to the constant curve set, see figure below.
Fig. 13 Constant curve mode
CRE, CRIE and CRNE pumps can be fitted with sensor
types meeting the requirements mentioned in the data
booklet titled "Grundfos E-pumps".

Operating and inlet
pressures
CR, CRI, CRN, CRE, CRIE, CRNE
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 must not be considered individually but must
always be compared, see the following examples:
Example 1:
The following pump type has been selected:
CR 5-16 A-A-A
Max. operating pressure: 16 bar
Max. inlet pressure: 10 bar
Discharge pressure against a closed valve: 10.6 bar,
see page 41.
This pump is not allowed to start at an inlet pressure of
10 bar, but at an inlet pressure of 16.0 – 10.6 = 5.4 bar.
Example 2:
The following pump type has been selected:
CR 10-2 A-A-A
Max. operating pressure: 16 bar
Max. inlet pressure: 8.0 bar
Discharge pressure against a closed valve: 2.0 bar,
see page 73.
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. operat-
ing 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.
In case the inlet or operating pressure exceeds the
pressure permitted, see "Lists of variants - on request"
page 79.

Selection and sizing
Selection of pumps
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)
• Shaft seal (see section 5).
1. Duty point of the pump
From a duty point it is possible to select a pump on the
basis of the curve charts shown in "Performance
curves" from page 29.
Fig. 15 Example of a curve chart
2. Dimensional data
When sizing a pump the following must be taken into
account:
• Required flow and pressure at the draw-off point.
• Pressure loss as a result of height differences
(Hgeo).
• Friction loss in the pipework (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 - NPSH", page 20.
Pump efficiency
Before determining the best efficiency point, the opera-
tion pattern of the pump needs to be identified.
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.
Fig. 16 Example of a CR pump’s duty point
As the pump is sized on the basis of the highest possi-
ble flow, it is important always to have the duty point to
the right on the efficiency curve (eta) in order to keep
efficiency high when the flow drops.

Selection and sizing CR, CRI, CRN, CRE, CRIE, CRNE
Normally, E-pumps are used in applications character-
ized by a variable flow. Consequently, it is not possible
to select a pump that is constantly operating at optimum
efficiency.
In order to achieve optimum operating economy, the
pump should be selected on the basis of the following
criteria:
• The max. duty point required should be as close as
possible to the QH curve of the pump.
• The required duty point should be positioned so that
P2 is close to the max. point of the QH curve.
Between the min. and max. 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. 19 Min. and max. performance curves
In situations where it is not possible to select a duty
point close to the 100% curve the below affinity equa-
tions 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 fre-
quency 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 pro-
grammes 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, Win-
CAPS 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 prod-
uct range covers the following three basic types.
• The CR(E), CRI(E) pump types are suitable for
clean, non-aggressive liquids such as potable wa-
ter, oils, etc.
• The CRN(E) pump type is suitable for industrial liq-
uids 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.
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:
• Oval flange (BSP)
• DIN flange
• PJE coupling
• Clamp coupling
• Union (+GF+)
• 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.
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.
Inlet pressure and operating pressure
The limit values stated on page 15 and page 16 must
not be exceeded as regards ...
• maximum inlet pressure and
• maximum operating pressure.

Minimum inlet pressure - NPSH
Calculation of the inlet pressure "H" is recommended
when
• the liquid temperature is high,
• the flow is significantly higher than the rated flow,
• 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 suction side of the pump. The maxi-
mum suction lift "H" in metres head can be calculated
as follows:
H = pb x 10.2 – NPSH – Hf – Hv – Hs
pb= Barometric pressure in bar.
(Barometric pressure can be set to 1 bar).
In closed systems, pb indicates the system
pressure in bar.
NPSH= Net Positive Suction Head in metres head.
(To be read from the NPSH curve at the
highest flow the pump will be delivering).
Hf = Friction loss in suction pipe in metres head.
(At the highest flow the pump will be deliver-
ing.)
Hv= Vapour pressure in metres head.
(To be read from the vapour pressure scale.
"Hv" depends on the liquid temperature "Tm").
Hs = Safety margin = minimum 0.5 metres head.
If the "H" calculated is positive, the pump can operate
at a suction lift of maximum "H" metres head.
If the "H" calculated is negative, an inlet pressure of
minimum "H" metres head is required.
Fig. 25 Minimum inlet pressure - NPSH
Note: In order to avoid cavitation never select a pump
with a duty point too far to the right on the NPSH curve.
Always check the NPSH value of the pump at the high-
est possible flow.

Guidelines to performance curves
The guidelines below apply to the curves shown on the
following pages:
• Tolerances to ISO 9906, Annex A, if indicated.
• The motors used for the measurements are stand-
ard 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
υ=1mm
2/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 per-
centage 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
Pumped liquids
Thin, non-explosive liquids, not containing solid parti-
cles or fibres. 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, if required.
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, tempera-
ture and content of chemicals, oils, etc.
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.
The CR(E), CRI(E), CRN(E) pump types are suitable
for the following liquids:
CR(E), CRI(E)
• Non-corrosive liquids.
For liquid transfer, circulation and pressure boosting of
cold or hot clean water.
CRN(E)
• Industrial liquids.
In systems where all parts in contact with the liquid
must be made of high-grade stainless steel.
CRT(E)
• Saline 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).
List of pumped liquids
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.
The table is intended as a general guide only, and can-
not 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
• concentration of the pumped liquid,
• liquid temperature or
• pressure.
may affect the chemical resistance of a specific pump
version.
Safety precautions must be made when pumping dan-
gerous 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 chrystallization/precipitation in shaft seal.
1The pumped liquid highly inflammable.
2The pumped liquid is combustible.
3Insoluble in water.
4Low self-ignition point.

Lists of variants - on request
Although the Grundfos CR(E), CRI(E), CRN(E) product
range offers a number of pumps for different applica-
tions, customers require specific pump solutions to sat-
isfy their needs.
Below please find the range of options available for
customizing the CR(E) pumps to meet the customers’
demands.
Contact Grundfos for further information or for requests
other than the ones mentioned below.
Motors
Shaft seals
Pumps
Connections and other variants
Variant Description
ATEX motor For operation in hazardous atmospheres, ex-
plosion-proof or dust-ignition-proof motors may
be required.
Motor with anti-
condensation
heating unit
For operation in humid environments motors
with built-in anti-condensation heating unit may
be required.
Motor with thermal
protection
Grundfos offers motors with built-in bimetallic
thermal switches or temperature-controlled
PTC sensors (thermistors) incorporated in the
motor windings.
Oversize motor
Ambient temperatures above 40°C or installa-
tion at altitudes of more than 1000 metres
above sea level require the use of an oversize
motor (i.e. derating).
4-pole motor Grundfos offers 4-pole standard motors.
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 O-
ring material.
Seal with flush,
quench seal Recommended for applications involving crys-
tallizing, hardening or sticky liquids.
Air-cooled shaft
seal system
Recommended for applications involving ex-
tremely 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 air-
cooled shaft seal system is recommended.
In order to ensure a low liquid temperature
around the standard shaft seal, the pump is fit-
ted with a special air-cooled shaft seal cham-
ber.
No separate cooling is required.
Double seal with
pressure chamber
Recommended for applications involving poi-
sonous 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 pres-
sure-intensifier generates the seal chamber
pressure.
CR MAGdrive
Magnetically driven pumps for industrial appli-
cations.
Key applications are industrial processes in-
voving the handling of aggressive, environmen-
tal, dangerous or volatile liquids, e.g. organic
compounds, solvents, etc.
Variant Description
Horizontally
mounted pump
For safety or height reasons, certain applica-
tions, 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, cool-
ant pumps may require neck-rings with a differ-
ent 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 mo-
tor, type MGE. The direction of rotation is the
opposite of that of standard pumps, and the
chamber stack is turned upside-down, as a re-
sult of which the pumped liquid flows in the op-
posite direction.
High-pressure
pump up to 47 bar
For high-pressure applications,Grundfos offers
a unique double pump system capable of gen-
erating a pressure of up to 47 bar pressure.
Low-NPSH pump
(improved suction)
Recommended for boiler-feed applications
where cavitation may occur due to poor inlet
conditions.
Pump with bearing
flange
The bearing flange is suitable for applications
where the inlet pressure is higher than the
maximum pressure recommended.
The bearing flange increases the life of motor
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 pharma-
ceutical and bio-
technological
applications
CRN(E) pumps designed for applications re-
quiring the sterilization and CIP capability of
pipes, valves and pumps. (CIP = Cleaning-In-
Place.)
Variant Description
Pipe connections
In addition to the wide range of standard flange
connections, a 16 bar DIN standard clamping
flange is available.
Customized flanges are available according to
specifications.
TriClamp
connection
TriClamp connections are of a hygienic design
with a sanitary coupling for use in the pharma-
ceutical and food industry.
Electropolished
pump
To substantially reduce the risk of corrosion of
the materials.
For use in the pharmacentical/food industry.
