Positive displacement pumps (PD) displace a known quantity of liquid with each revolution of the pumping elements. This is done by trapping liquid between the pumping elements and a stationary casing. Pumping element designs include gears, lobes, rotary pistons, hose, diaphragms, vanes, and screws.

PD pumps are found in a wide range of applications chemical processing; liquid delivery; marine; biotechnology; pharmaceutical; as well as food, dairy, and beverage processing.

Their versatility and popularity is due in part to their compact design, high- viscosity performance,  continuous flow regardless of differential pressure, and ability to handle high differential pressure.
