8. Mechanical installation
8.1 Preparations before installation
The contractor must inspect the equipment on
delivery and make sure that it is stored in such a way
that corrosion and damage are avoided. If more than
six months will pass before the equipment is put into
operation, please consider applying a suitable
corrosion inhibitor to the internal pump parts.
Ensure that the corrosion inhibitor used does not
affect the rubber parts with which it comes into
contact.
Ensure that the corrosion inhibitor can easily be
removed.
To prevent water, dust, etc. from entering the pump,
all openings must be kept covered until the pipes are
fitted. The cost of dismantling the pump during
startup to remove a foreign object can be very high.
Mechanical shaft seals are precision components. If
the mechanical shaft seal of a recently installed
pump fails, this will normally happen within the first
few hours of operation. The main cause of such
failures is improper installation of the shaft seals
and/or mishandling of the pump during installation.
During transport, the pump must be fastened
securely to prevent damage to the shaft and seal
caused by excessive vibrations and knocks. The
pump must not be lifted by means of the shaft.
8.2 Pump location
The pump should be sited in a well-ventilated, but
frost-free location.
For inspection and repair, allow suitable clearances
for pump or motor removal.
Vertical installation
• Pumps fitted with motors up to and including 4
kW require a 0.3 m clearance above the motor.
• Pumps fitted with motors of 5.5 kW and up
require at least a 1 metre clearance above the
motor to allow the use of lifting equipment.
Fig. 9 Clearance above the motor
Horizontal installation
• Pumps fitted with motors up to and including 4
kW require a 0.3 m clearance behind the motor.
• Pumps fitted with motors of 5.5 kW and up
require a 0.3 m clearance behind the motor and
at least a 1 metre clearance above the motor to
allow the use of lifting equipment.
• NB pumps with base frame must have the same
clearance as pumps with motors from 5.5 to 200
kW.

Warning
When pumping hot liquids, care should be
taken to ensure that persons cannot
accidentally come into contact with hot
surfaces.
