Boiler feed pump sizing calculations
WebRemember that the static head is the difference in height that the pump will be required to provide. In the drawing below, showing a cooling tower, the static height might appear to be 40’. However, the water level in the tower sump is 28’ above the pump, so the pump must only provide a net lift of 12’. Therefore, the static head is 12’.
