a measure of how close the fluid at a given point is to flashing, and so to cavitation.

To pump the fluid without cavitation noise and vibration, the minimum required pressure at suction side is known as pump suction head.

A Pump is a mechanical device used to transfer liquids from one point to other by imparting energy supplied by a prime mover to the liquid. The prime mover can be an electric motor, an I.C. engine, or a steam engine or turbine

Pump, a device that expends energy in order to raise, transport, or compress fluids

Pump suction head is only use may flow and dependent head to flow increase and decrease

When the source of supply is below the pump level, then the head required to lift the fluid is suction head
