1.4 Permanent magnets

WARNING

Magnetic field

Death or serious personal injury

‐Persons with pacemaker or other

magnet-sensitive medical devices must

not handle this pump. They must keep

a distance of at least 1 metre from the

product, as there is a risk of influence

from the magnetic fields of the pump.

‐Credit cards, computers, watches and

other magnet-sensitive objects should

not be kept close to the pump.

‐The pump contains powerful magnets

that may pose a risk of personal injury

when servicing the pump. The pump

must therefore only be dismantled and

assembled by authorised persons.

2. Product introduction

2.1 Product description

Incorrect operation of the pump can result

in malfunction or damage to the pump and

damage to the surrounding property.

Grundfos CRN MAGdrive pumps are semi-hermetic

and essentially leakage-free. The motor torque is

transmitted to the pump shaft by means of magnetic

force.

3. Mechanical installation

Installation and operation must comply

with local regulations and accepted codes

of good practice.

Before installation, check that the pump and its

components are as ordered and that no visible parts

have been damaged.

3.1 Installing the product

WARNING

Magnetic field

Death or serious personal injury

‐Persons with pacemaker or other

magnet-sensitive medical devices must

not handle this pump. They must keep

a distance of at least 1 metre from the

product, as there is a risk of influence

from the magnetic fields of the pump.

WARNING

Falling objects

Death or serious personal injury

‐Fasten the pump securely to a solid

and even foundation according to the

specifications stated in the installation

and operating instructions.

The pump must not be installed in ATEX

zones 2D, 3D and M2 (dust and mining

zones).

If the pump is installed in ATEX zones 2G

or 3G, a LiqTec sensor must be installed to

protect the pump.

The pump must be installed and put into operation as

described in the installation and operating instructions

for CR, CRI, CRN.

We recommend to protect CRN MAGdrive pumps

against dry running by installing a flow switch,

pressure switch or a LiqTec sensor close to the pump.

The delay of the dry-running protection must be

maximum 15 seconds.

English (GB)

3.2 Connection of a sensor

A pressure sensor or a Grundfos LiqTec dry-running

protection unit can be fitted in the threaded hole in the

pump head.

Description Dimension

Threaded connection: RG 1/2

Max. installation length, sensor: 20 mm

4. Electrical connection

WARNING

Electric shock

Death or serious personal injury

‐Switch off the power supply before you

start any work on the product.

‐Make sure that the power supply

cannot be switched on accidentally.

‐Connect the pump to an external main

switch close to the pump and to a

motor-protective circuit breaker or a

CUE frequency converter. Make sure

you can lock the main switch in OFF

position (isolated). Type and

requirements as specified in EN

60204-1, 5.3.2.

The pump must be installed as described in the

installation and operating instructions for CR, CRI,

CRN.

Pumps with 2-pole motors of 18.5 and 22 kW and 4-

pole motors as from 1.1 kW must be started via a soft

starter.

4.1 Motor protection

As a minimum, the motor must be connected to an

effective electronic motor protection with

instantaneous release when the maximum current

setting is reached. If a soft starter or a frequency

converter is used, it must also be with instantaneous

release.

To ensure the optimum protection of the MAGdrive

motor, the motor protection must be set in

accordance with the following guidelines:

1. Set the overload protection to the rated full-load

current (I1/1) of the motor.

2. Start the pump, and let it run for half an hour at

the required duty point.

3. Measure the motor current. If not possible, slowly

grade down the scale indicator until the motor trip

point is reached.

4. The setting of the motor protection must be 5 %

higher than this value. The highest permissible

setting of the motor protection is the rated full-load

current (I1/1) of the motor.

4.2 Self-regulating heat-tracing cable

If the pump is supplied with a self-regulating heat-

tracing cable, make sure that the cable is connected

to a 1 x 220-240 V, 50 Hz power supply.

If the pump operates with liquids below 0 °C, ensure

that the power supply is switched on, even if the

pump is stopped. The power supply must not have a

fuse size larger than 13 A.

5. Starting up the product

DANGER

Explosion risk

Death or serious personal injury

‐Always fill the pump with liquid and

ensure that the required minimum flow

rate is obtained.

WARNING

Magnetic field

Death or serious personal injury

‐Persons with pacemaker or other

magnet-sensitive medical devices must

not handle this pump. They must keep

a distance of at least 1 metre from the

product, as there is a risk of influence

from the magnetic fields of the pump.

WARNING

Corrosive liquids

Death or serious personal injury

‐Wear personal protective equipment.

WARNING

Toxic liquids

Death or serious personal injury

‐Operation and servicing of the pump

may pose a risk to the life and health of

the persons involved if the pumped

liquid is flammable, aggressive,

corrosive, toxic, or in any other way

harmful.

‐Wear personal protective equipment.

CAUTION

Hot or cold liquids

Minor or moderate personal injury

‐Wear personal protective equipment.

CAUTION

Hot or cold surface

Minor or moderate personal injury

‐Make sure that no one can accidentally

come into contact with hot or cold

surfaces.

Do not start the pump until it has been

filled with liquid and vented.

1. Open the isolating valve on the inlet side of the

pump.

2. Close the isolating valve on the outlet side of the

pump.

3. Loosen the vent screw in the pump head.

4. Slowly fill the pump with liquid.

5. Tighten the vent screw when the pump has been

completely filled with liquid.

6. Slowly open the isolating valve on the outlet side

of the pump.

7. Start the pump.

8. Check the direction of rotation by means of the

motor fan and the label on top of the fan cover.

9. After startup, the pump must be vented again.

Slowly loosen the vent screw in the pump head.

Pay attention to the direction of the

vent hole during liquid filling and

venting. Make sure that the escaping

liquid does not cause damage to the

motor or other components.

10. When liquid runs out, tighten the vent screw

securely.
