Pump unit handling

Use an overhead crane, forklift or other suitable lifting device.

front part of the pump and the
back part of the motor. Make
sure that the load is balanced
before attempting the lift.

slings.
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.
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.
6
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 result in
personal injury and/or damage
to the unit.
