‘Head’ and ‘pressure’ in pumps Water Tech Online

Differential pressure. Allow me to refine a couple of points: Pumps develop differential head, or differential pressure. This means the pump takes suction pressure, adds more pressure (the design pressure), and generates discharge pressure. So, the discharge pressure is equal to the suction pressure plus the pump’s design pressure.

H 1 and H 2 represent the pressure heads corresponding to the pressures in the tanks p 1 and p 2. If the tanks are open to atmosphere that H 1 and H 2 will equal zero. It is always possible to calculate pressure head when the pressure is known using
