Recommended
Discharge priming valve.
Non-slam or spring loaded check valve.
Support piping
as required.
Isolation Valve
Isolation valve to permit servicing
of check valve or pump.
Discharge pipe diameter at lest one nominal
pipe six larger than discharge opening size.
This fitting may be used to check shut-off head.

discharge fittings typical of
pump with suction lift.
Pressure Gauge
Expansion joint with tie rods where needed.
Align piping to minimize
flange stress.
Use Concentric Reducer to
minimize friction losses.
