1.3.2 Pump units
1.3.2.1 Pump unit handling
Use an overhead crane, forklift or other suitable lifting device.
Secure lifting slings around the front
part of the pump and the back part of
the motor. Make sure that the load is
balanced before attempting the lift.
NB! Always use two lifting slings.
If there are lifting rings on both the
pump and the motor the slings may be
fastened to these.
NB! Always use two lifting slings.
Warning
Never lift the pump unit with only one
fastening point. Incorrect lifts can re-
sult in personal injury and/or damage
to the unit.
1.3.2.2 Installation
All pump units should be equipped with a locking safety switch to prevent accidental start during
installation, maintenance or other work on the unit.
Personnel who have a pacemaker should not be allowed to work with the magnetic
coupling!
The magnetic field is sufficiently strong to affect the operation of a pacemaker. A safe
distance is 3 metre!
Always keep electronic equipment with memory, cheque cards with magnetic strips,
and similar items at least 1 metre away from the coupling!
Warning
The safety switch must be turned to off and locked before any work is carried out on the pump unit.
Accidental start can cause serious personal injury.
The pump unit must be mounted on a level surface and either be bolted to the foundation or be fitted
with rubber-clad feet.
The pipe connections to the pump must be stress-free mounted, securely fastened to the pump and
well supported. Incorrectly fitted pipe can damage the pump and the system.
Warning
Electric motors must be installed by authorized personnel in accordance with EN60204-1. Faulty
electrical installation can cause the pump unit and system to be electrified, which can lead to fatal
injuries.
Electric motors must be supplied with adequate cooling ventilation. Electric motors must not be
enclosed in airtight cabinets, hoods etc.
Dust, liquids and gases which can cause overheating and fire must be diverted away from the
motor.
Warning
Pump units to be installed in potentially explosive environments must be fitted with an Ex-class
(explosion safe) motor. Sparks caused by static electricity can give shocks and ignite explosions.
Make sure that the pump and system are properly grounded. Check with the proper authorities for
the existing regulations. A faulty installation can lead to fatal injuries.
