5.3.2 Set-up
•
The pump materials and protective layers are
suitable for indoor set-up and a protected
outdoor set-up. Under certain conditions the
pump is suitable for limited outdoor set-up or a
salty or aggressive atmosphere. Consult your
Bredel representative for more information.
•
Position the pump on a horizontal surface. Use
suitable anchor bolts to attach the pump to the
floor surface.
•
Make sure that there is sufficient room around
the pump to carry out the necessary
maintenance activities.
•
Make sure that the room is sufficiently
ventilated, so that the heat developed by the
pump and drive can be discharged. Keep some
distance between the ventilation cover of the
electric motor and wall to enable the supply of
necessary cooling air.
5.3.3 Pipework
When determining and connecting suction and
discharge lines consider the following points:
•
The bore size of the suction and discharge lines
must be larger than the bore size of the pump
hose. For more information consult your Bredel
representative.
•
Limit the presence of sharp bends in the
discharge line. Make sure that the radius of the
bent discharge line is as large as possible
(preferably 5S). It is recommended to use Y-
connections instead of T-connections.
•
Keep the piping at a minimum equal to or
greater than the bore size of the pump. Increase
the bore size of the pipe work when the duty
fluid has a high velocity or inertia. This will help
keep friction and impulse losses to a minimum.
Where critical velocities are a concerned,
consult your Bredel representative.
