Static suction head of a pump

WebMay 22, 2012 · STATIC SUCTION HEAD The vertical distance between the pump impeller and the surface of the liquid on the suction side of the pump. WATER HAMMER Energy transmitted back to the pump due to the sudden stoppage of water flowing from the pump. More likely to occur when using a long discharge hose. WebNote that NPSH is equivalent to the sum of both the static and dynamic heads – that is, the stagnation head – minus the equilibrium vapor pressure head, hence "net positive suction head". ... Experimentally, NPSH R is often defined as the NPSH 3, the point at which the head output of the pump decreases by 3 % at a given flow due to reduced ...
