WebHeadis the height above the suction inlet that a pump can lift a fluid. It is a shortcut measurement of system resistance (pressure) which is independent of the fluid's specific gravity. It is defined as the mechanical energy of the flow per unit weight. It is expressed as a column height of water given in feet (ft) or meters (m).
WebConsidering the design trim curve we see that at zero flow, also known as shutoff or dead-head, the pump will develop about 130 ft of head. This is the head the pump would develop if it were operating against a closed … WebSimply stated, a pump’s head is the maximum height that the pump can achieve pumping against gravity. Intuitively, if a pump can produce more pressure, it can pump water higher and produce a higher head. The …
