professional dealer. Install pump in a clean, dry and
drained location readily accessible for inspection and
maintenance. Provide ample ventilation.
Pump Foundation
Heavy parts. Use care and proper equipment
when handling pump for installation. Pump should be set
on a concrete foundation which is sufficiently substantial
to absorb vibration and which provides a permanent and
rigid support.
There are several types of permanent pump / foundation
installations in use. Those pictured here are typical.

liquid from pooling.
Piping
System piping should be at least one commercial pipe
size larger than pump connections and flow velocity
should not exceed eight (8) feet per second.
NOTICE Take care to align piping with pump case.
Misalignmentorexcessivepipestraincancause
distortion of pump components resulting in rubbing,
breakage and reduced pump life.
Support pipe in such a way that no force is exerted on
pump connections. Check alignment as follows: with the
pump shut down and isolation valves closed, remove
pipe flange bolts. If the mating flanges come apart or
shift, misalignment is present and causing pressure
on the connections. Adjust pipe supports until flanges
mate without any force. This procedure can be done
throughout piping system.
