1. MINIMUM INLET (SUCTION) PRESSURE
In general, the minimum suction pressure required
is that which provides adequate NPSH
A
necessary to
feed the pump. The required NPSHr, expressed in
feet, can be found on the performance curve for the
pump at the specific duty point. It is recommended
that the NPSH
A
exceeds the NPSHr by a minimum
of (2) two feet as a safety margin and to insure long
term reliable performance of your e-SV pump.
