Pentair BERKELEY B85580 Manuel Du Propriétaire page 10

Pump driven by remote power
source, direct coupling or
pulley/belt connection.
See foundation
section.
Straight run, short as possible but
at least 6 times pipe diameter after
pipe fitting to stabilize flow.
Slope upward to pump.
• Use pipe, tubing, or reinforced hose to make suction
connection. Hose must have sufficient strength to
resist collapse under the atmospheric pressure
differential that may occur while pump is running.
• It is important, even with a flooded suction condition,
that proper pipe fittings are used so water is delivered
to impeller eye with a smooth flow and consistent
velocity.
• Suction pipe size should be at least one commercial
pipe size larger than opening of pipe inlet. Flow
velocity should not exceed 8 ft./sec.

Suction Connection
When Flooded Suction Exists
Short run of straight pipe after reducer
(2 times pipe diameter).
Eccentric Reducer
flat side up.
Suction
Gauge
Recommended
Maintain minimum liquid
level to prevent vortexing.
Isolation Valve
full open when
pumping.
Support pipe
as required
• An isolation valve is used in a pressurized suction
pipe to permit servicing pump.
• Piping run and connection fittings should be properly
aligned and independently supported to reduce strain
on pump case.
• If solids are present, a strainer should be used to
protect the pump.
