WebNext, there’s the P2-curve. The P2-curve measures the relation between a pump’s power consumption and flow. For most centrifugal pumps, the P2 value increases when the flow increases. Finally, there’s the NPSH-curve. NPSH stands for net positive suction head and denotes the minimum absolute pressure that must be present at the suction ... WebThe pump performance curve describes the relation between the flowrate and the head for the actual pump. Other important information for a proper pump selection is also included - like efficiency curves, NPSH r curve, pump curves for several impeller diameters and different speeds, and power consumption. Increasing the impeller diameter or ... WebNPSH is an acronym that stands for Net Positive Suction Head. NPSH is a measure of the absolute pressure present in a liquid.
