These fluids are usually pumped from a lower level to a higher level. The pump is located between these levels. ... This means that the pump does not suck in liquid at all. Rather, the (ambient) pressure on the surface of the liquid pushes the fluid into the pump. ...

WebThe static head is created by any vertical columns of liquid attached to the pump and any pressurized systems attached to the pump outlet. The static head exists under static conditions, with the pump switched off, and does 3 not change based on flow. The height of fluid above the pump’s centerline can be determined from the plant layout drawing. WebIn a hydraulic circuit, net positive suction head (NPSH) may refer to one of two quantities in the analysis of cavitation: . The Available NPSH (NPSH A): a measure of how close the fluid at a given point is to flashing, and so to cavitation.Technically it is the absolute pressure head minus the vapour pressure of the liquid.
