PDF Design of Sewage Pumping Stations The two elements of the system head curve are 1 the static head and 2 the friction head. 1 Static head is defined as the vertical lift of the fluid that the pump has to overcome. It is assumed to be a constant head after the station is put into operation for a baseline of the system head curve. It is defined as follows: Static Head = Highest elevation opened to the atmosphere* minus the system’s low point**

PDF Pump Station Design Guidelines Second Edition Pump Station Design Guidelines ... the static head is not a fixed value, but rather a floating value dependent upon the water surface elevation in the wet well.

HOW TO design a pump system Static head is sometimes called total static head to indi e that the pressure energy available on both sides of the pump has been considered. Since there is a difference in height between the suction and discharge flanges or connections of a pump by convention it was agreed that the static head would be measured with respect to the suction flange elevation.
