WebJan 15, 2024 · As RPM increases, the pump flow increases, from 0 gallons per minute or (GPM) at 0 RPM, to about 130 GPM at 500 RPM. Fig. 1. A PD pump curve indicates pump capacity, on the horizontal lines, in units per minute. In this example, the curve indicates gallons per minute (GPM) and liters per minute (LPM) in the left margin and the vertical … WebThe second characteristic for pump sizing is the pump head or discharge pressure. The term “head” derives from the height of water that the pump can overcome at a given flow, generally expressed as feet of water (1 foot water = 0.43 psi = 6.3 bar). Operators often think of head as the discharge pressure at the pump, but many different ...
Webcurve and move vertically to the BHP curve. At this intersection, move horizontally to the right-hand scale to read the BHP at that flow. The curve shapes in figures 1-3 are typical of centrifugal wheels. Other impeller types have both fan and power curve shapes that vary from those shown.
