Hi
If i change my pump motor from 18.5 kw to 11kw is there a way to calculte the new flow and pressure the pump will deliver( assuming the impellers etc remain the same)

RE: changing motor power
The bhp of the pump has not changed. If the bhp is higher than 11kw you will over load the driver.

How long will the lift take if I reduce the force applied to 50 lbs?
RE: changing motor power
In English units: BHP = [head(FT) x flow(GPM) x SG] / [3960 x eff.] Convert the resulting BHP to kw units and if it is less than 11 kw, then there should be no change in the pumps operating point.
