3. Product description
Grundfos CRN MAGdrive are 100 % leakage-free, sealless
pumps. The motor torque is transmitted to the pump shaft by
means of magnetic force.
Grundfos CRN MAGdrive pumps are suitable for the pumping of
these liquids:
• Aggressive or corrosive liquids
• Toxic liquids
• Volatile liquids
• Obnoxious liquids
• Liquids without fibres and magnetic particles, as they may
cause wear of the pump.
Warnin g
If these safety instructions are not observed,
it may result in personal injury!
If these safety instructions are not observed,
it may result in malfunction or damage to the
equipment!
Notes or instructions that make the job easier
and ensure safe operation.
2. Permanent magnets
Warnin g
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 MAGdrive, 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.
Warnin g
The pump contains powerful magnets that may
pose a risk of personal injury when servicing the
pump. The pump should therefore only be
dismantled and assembled by authorised
personnel.

6. Mechanical installation
Warnin g
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.
• no visible parts have been damaged.
6.1 Installation of pump
The pump must be installed and put into operation as described
in the installation and operating instructions of CR, CRI, CRN.
It is advisable 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.
6.2 Connection of sensor
A pressure sensor or a Grundfos LiqTec dry-running protection
can be fitted in the threaded hole in the pump head.
Description Dimension
Threaded connection: RG 1/2
Max. installation length, sensor: 20 mm
7. Electrical connection
The pump must be installed as described in the installation and
operating instructions of 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.
7.1 Motor protection
As minimum the motor must be connected to an effective
electronic motor protection with instantaneous release when the
maximum setting of the current is reached. If a soft starter or a
frequency converter is used it must also be with instantaneous
release.
In order to ensure the optimum protection of th e M AGdrive mo tor,
the motor protection should be set in accordance with the
following guidelines:
1. Set the overload protection to the rated full-load current (I
of the motor.
1/1
)
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 (I
) of the motor.
1/1
8. Start-up
Do not start the pump until it has been filled with
liquid and vented.
1. Open the isolating valve on the suction side of the pump.
2. Close the isolating valve on the discharge side of the pump.
3. Loosen the air vent screw in the pump head.
4. Slowly fill the pump with liquid.
5. Tighten the air vent screw when the pump has been
completely filled with liquid.
6. Slowly open the isolating valve on the discharge 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 start-up, the pump should be vented again.
Slowly loosen the air vent screw in the pump head.
Warnin g
Pay attention to the direction of the vent hole to
ensure that the escaping liquid does not cause
injury to persons or damage to the motor or other
components.
10.When liquid starts running out, tighten the air vent screw
securely.
9. Maintenance
The pump requires no maintenance if is has been installed
according to the instructions.
