'Head' and 'pressure' in pumps | Water Technology

Oct 13, 2010· 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.
