Positive Displacement Pump. Physically moves fixed volume of liquid from suction to discharge conditions. Provides constant volume of fluid pumped per stake or revolution, less any slip (Leakage) back to section.

A Positive Displacement Pump, unlike a Centrifugal or Roto-dynamic Pump, will produce the same flow at a given speed (RPM) no matter the discharge pressure. A Positive Displacement Pumps is a " constant flow machine "
Centrifugal pumps use centrifugal force to move fluid, while positive displacement pumps use a mechanical means, such as a piston or a rotor, to move fluid.
Positive displacement pumps, such as the diaphragm, screw and rotary pumps, are designed to reduce contact between moving parts and the pumping fluid. This allows them to handle abrasive or shear-sensitive substances better, a beneficial characteristic for sectors like mining or chemical processing.
Positive Displacement Pump consisting of a chamber containing gears, cams, screws, vanes, plungers or similar elements operated by relative motion of the drive shaft
