Pump Curve
Pump Curve
(OP)
Good day,
I am trying to approximate the performance of a pump onsite. When plotting the point on the curve, the Total head the pump is operating at does not correspond to the flow its delivering. The flow its ACTUALLY delivering is around 5,100 gpm, while the flow it's SUPPOSED to deliver based on the curve is around 3500 gpm. The way the system is designed, the pump doesnt have a choice but to pump this flow of 5100 gpm. I checked the hydraulic power curve and it matches the power used by the motor (taking efficiencies into account)to deliver the flow of 5100. Is it possible for a pump to operate like this??

RE: Pump Curve
A pump curve is defined as all of the operating points that a particular pump is capable of running at. If you are plotting the pump performance 46% greater in flow than shown on the curve, then you have bad data or the wrong curve for that pump.
