WebNO. The recommended NPSH margin for a centrifugal pump does not change at higher elevations. The NPSH required (NPSHr) by the pump also does not change with altitude. Altitude does, however, affect NPSH available (NPSHa). Therefore, as atmospheric pressure is decreased at higher altitudes, the NPSHa reduces. WebThe shut-off head is one of the most important parameters in the pump. It is defined as the head with respect to zero volumetric flow rate. Pump Static head. Static head means the height difference between the elevation of the source of liquid and the elevation of the discharge liquid. Suction static head is totally depending on the elevation.
