Understanding Centrifugal Pump Curves
pump at a rate of 140 gallons per minute. Typical centrifugal pumps will show an increased flow rate as head pressure decreases. The curve also shows the shut off head or the head that the pump would generate if operating against a closed valve. In our same example, the shutoff for the 7.9” impeller is 45 ft of head.

www.mgnewell.com(Net Positive Suction Head available) NPSHa = Pa ± h s – h fs – Pvp (+h s for flooded section) (-h s for suction lift) where: Pa = pressure absolute above fluid level (bar) h s = static suction head (m) h fs = pressure drop in suction line (m) Pvp = vapor pressure (bar a) Or Pa = pressure absolute above fluid level (psi) h s = static ...
Understanding Centrifugal Pump Curves
www.mgnewell.comUnderstanding Centrifugal Pump Curves When selecting a centrifugal pump, one should match the performance of the pump to that needed by the system. To do that, an engineer would refer to a pumps composite curve. A typical composite curve includes the pump performance curves, horsepower curves and NPSH required.

Static head (H s): It is sum of suction head and delivery head. It is given by H s = (h s + h d) 4. Manometric head (H m): The head against which the centrifugal Pump has to work.

Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs. Since, worldwide, centrifugal pumps account for the majority of electricity used by pumps, the focus of this chapter is on centrifugal pump.
