Suction-piping checklist
Performance curve reference
CAUTION:
Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the suction
side. This action can result in decreased performance, unexpected heat generation, and equipment damage.
Net positive suction head available (NPSH
A
) must always exceed NPSH required (NPSH
R
) as shown on
the published performance curve of the pump.
Suction-piping checks
Check
Explanation/comment
Checked
Check that the distance between the inlet flange of
the pump and the closest elbow is at least five pipe
diameters.
This minimizes the risk of cavitation in
the suction inlet of the pump due to
turbulence.
See the Example sections for
illustrations.
