INSTALLATION
LOCATION
Place the pump as close to the water source as practical. Make the
pipe run as short and straight as possible, especially if a suction lift
is required.
Careful attention should be taken to ensure that net positive
suction head available (NPSHA) exceeds net positive suction head
required (NPSHR) by the pump. Not doing so may result in reduced
performance or severe pump damage. Contact your nearest Pentair
Pentair Sta-Rite

authorized dealer for installation assistance. 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
provides a permanent and rigid support.
There are several types of permanent pump/foundation installations
in use. Those pictured here are typical.
• If grout is used, top of concrete should be left rough to provide a
good bonding surface.
• Foundation should slope away from the pump to prevent liquid
from pooling.
PIPING
System piping should be at least one commercial pipe size
larger than pump connections and flow velocity should not exceed
8 ft/sec.
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:
1. Shut down pump and close isolation valves.
2. Remove pipe flange bolts.
3. If the mating flanges come apart or shift, misalignment is
present and causing pressure on the connections.
4. Adjust pipe supports until flanges mate without any force.
This procedure can be done throughout piping system.
Refer to pages 8 and 9 for recommended practices and guidance
for suction connections in centrifugal pump installations.
