Installation • Suction Connection
When Flooded Suction Exits
• Suction piping that is undersized will create excess
friction losses that may cause cavitation and a
reduction in pump performance.
• Excess fittings and bends in suction line result in
trapped air, reduced performance, and high friction
losses which may cause cavitation.
• If check valve is required for back flow prevention,
locate on the discharge side of pump.
Inverted Eccentric Reducer
may result in air pocket.
Check Valve
in suction pipe
not needed.
Concentric Reducer may
cause air pockets.
Not Recommended
Valve in upward
position may trap
air.
Do not leave
valve partially
closed.
Unsupported
pipe causes
excessive stress
on pump and fittings.
Miter elbow, short radius
elbow, and double elbows
not recommended.
