1. Product introduction

This data booklet covers Grundfos CR and CRN

pumps with these nominal flow sizes:

• CR, CRN 95

• CR, CRN 125

• CR, CRN 155.

Fig. 1 CR, CRN 95-155

CR, CRN pumps are vertical multistage, centrifugal

pumps. The in-line design of the pumps enables

installation in a horizontal one-pipe system where the

inlet and outlet ports are in the same horizontal level

and have the same pipe dimensions. This design

provides a more compact pump design.

The pumps are available in various sizes and various

numbers of stages to deliver the flow and pressure

required.

CR, CRN pumps are designed for a variety of

applications ranging from the pumping of potable water

to the pumping of chemicals. The pumps are therefore

suitable for a wide diversity of pumping systems where

the performance and material of the pump meet

specific demands.

A CR, CRN pump consists of two main components:

the motor and the pump unit.

The pump unit consists of optimized hydraulics,

various types of connections, a sleeve, a pump head

and various other parts. See Construction, page 8.

CR, CRN pumps are available in various material

versions according to the pumped liquid.

CR pumps with ANSI/NSF 61 and ANSI/NSF 372

listing are available. FKM variants are only available

with ANSI/NSF 372 listing. See UL file MH24600 or

contact Grundfos.

Applications

The new CR, CRN range is suitable for numerous

applications identical to the applications which the

current CR, CRN pumps handle today. The following

applications are some typical examples.

Water supply:

• Filtration and transport water works

• Distribution from water works

• Pressure boosting of mains.

Industrial:

• Pressure boosting

• Process water transfer

• Boiler feed

• Cooling and air conditioning

• Firefighting systems

• District energy systems

• Special liquids transfer.

Water treatment:

• Filtration

• Brackish water reverse osmosis.

Pumped liquids

Thin, non-explosive liquids, not containing solid

particles or fibers. The liquid must not attack the pump

materials.

CR pumps are suitable for non-corrosive liquids and

are to be used for liquid transfer, circulation and

pressure boosting of cold or hot clean water.

CRN pumps are suitable for industrial liquids and are

to be used in systems where all parts in contact with

the liquid must be made of high-grade stainless steel.

For further details see List of pumped liquids, page 31.

Product introduction

CR, CRN 95-155 1

Pump

The CR pumps are non-self-priming, vertical

multistage centrifugal pumps.

The pumps are available with a Grundfos or Baldor

standard motor.

The pump consists of a base and a pump head. The

chamber stack and the sleeve are secured between

the base and the pump head by means of staybolts.

The base has inlet and outlet ports on the same level

(in line). All pumps are fitted with a maintenance-free

mechanical shaft seal of the cartridge type.

Fig. 3 CR pump

Motor

Grundfos ML standard and Baldor motors

CR, CRN pumps are fitted with a totally enclosed,

fan-cooled, 2-pole Grundfos or Baldor standard motor.

Angular contact bearings are fitted to the drive end on

motors up to 75 Hp (56 kW). This ensures that the

motor bearing life (L10) is extended to match that of

the pump.

Electrical data

* A different enclosure type is available on request.

** Different voltages are available on request.

Grundfos E-motors

We also offer frequency-controlled CRE, CRNE pumps

which are the ideal choice for a number of applications

characterized by a demand for variable flow at

constant pressure. These 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.

Optional motors

The Grundfos standard range of motors covers a wide

variety of application demands. However, for special

applications or operating conditions, custom-built

motor solutions can be provided.

For special applications or operating conditions, we

offer custom-built motors such as

• Explosion-proof motors

• Motors with anti-condensation heating unit

• motors with thermal protection.

Motor protection

Single-phase Grundfos motors have a built-in thermal

overload switch (TP 211 according to IEC 34-11).

Three-phase motors must be connected to a

motor-protective circuit breaker according to local

regulations.

Three-phase Grundfos ML motors 5 Hp ( 5 kW) and

larger have a built-in thermistor (PTC) according to

DIN 44082 (TP 211 according to IEC 34-11).

Terminal box positions

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

of the pump.

Fig. 4 Terminal box positions

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 must be fitted with a

larger motor. If in doubt, contact Grundfos.
