Positive Displacement Pumps - an overview ScienceDirect ...

Positive displacement pumps include gear pumps, piston pumps, plunger pumps, and progressing cavity pumps. All PD pumps have in common the fact that they are volumetric devices in which a fixed volume of fluid is drawn into the pump, pressurized, and discharged at high pressure into the line.
