Product overview

Introduction

This data booklet deals with CR, CRI and CRN as well

as CRE, CRIE and CRNE pumps.

CR, CRI, CRN

Fig. 1 CR, CRI and CRN pumps

CR,CRI,CRNpumps are vertical multistagecentrifugal

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.

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 variety 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 on a CR pump is a

heavy-duty Grundfos specified motor.

The pump unit consists of optimized hydraulics, various

typesofconnections, an outersleeve, a top and various

other parts.

CR pumps are available in various material versions

according to the pumped liquid.

CRE, CRIE, CRNE

Fig. 2 CRE, CRIE and CRNE pumps

CRE, CRIE, CRNE pumps are built on the basis of CR,

CRI, CRN pumps.

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

pump family and are referred to as E-pumps.

The difference between the CR and the CRE pump

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

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

control.

The motor of the CRE pump is a Grundfos MLE motor.

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.

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, 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.

Product overview CR, CRI, CRN, CRE, CRIE, CRNE

Pump

The CR and CRE pump is a non-self-priming, vertical

multistage centrifugal pump. The pumps are available

with a Grundfos standard motor (CR pumps) or a

frequency-controlled motor (CRE pumps).

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

chamber stack and the outer sleeve are secured

between the pump head and the base by means of

staybolts. The base has suction and discharge ports on

the same level (in-line).

All pumps are equipped with a maintenance-free

mechanical shaft seal of the cartridge type.

Fig. 3 CR pump

CR pump with ANSI/NSF 61 listing is available. See UL

file MH26400 or contact Grundfos.

Motor

Grundfos standard motors - ML and Baldor® motors

CR, CRI and CRN pumps are fitted with a Grundfos

specified motor. The motors are all heavy-duty 2-pole,

NEMA C-face motors.

Frequency-controlled motors - MLE motors

CRE, CRIE and CRNE pumps are fitted with a totally

enclosed, fan-cooled, 2-pole motor with integrated

variable frequency drive.

From 0.5 Hp to 1.5 Hp Grundfos offers CRE pumps

fitted with single-phase MLE motors (1 x 208-230 V).

From 1.0 Hp to30 Hp GrundfosoffersCREpumps fitted

with three-phase MLEmotors (3 x 460-480 V). From 1.5

Hp to 7.5 Hp Grundfos offers CRE pumps fitted with

three-phase MLE motors (3 x 208-230 V).

Electrical data

Optional motors

The Grundfos standard range of motors covers a wide

variety of application demands. However, for special

applicationsoroperatingconditions, custom-built motor

solutions can be provided.

For special applications or operating conditions,

Grundfos offers custom-built motors such as:

• explosion proof motors,

• motors with anti-condensation heating unit,

• low-noise motors,

• premium efficiency motors,

• motors with thermal protection.

Motor protection

Single-phase Grundfos specified motors up to 7.5 hp

have a built-in thermal overload switch.

Three-phase motors must be connected to a motor

starter in accordance with local regulations.

Terminal box positions

As standard the terminal box is mounted on the suction

side of the pump.

Fig. 4 Terminal box positions

Ambient temperature

Ambient temperature: Maximum +104 °F.

If the ambient temperature exceeds +104 °F or if the

motor is located 3280 feet above sea level or higher,

the motor output (P2) must be reduced due to the low

cooling effect of the air. In such cases, it may be

necessary to use a motor with a higher output.

Fig. 5 Relationship between motor output (P2) and

ambient temperature

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.
