A distinction is made according to the movement type of the displacer. The types are rotary and reciprocating positive displacement pumps.Oscillating positive displacement pumps include

Piston pump
Diaphragm pump

The following constructions are counted among the rotating positive displacement pumps:

Screw pump
Progressing cavity pumps (eccentric screw pumps)
Rotary lobe pump
Gear pump
Screw pump
Peristaltic pump

In opposition to the centrifugal pumps the positive displacement pumps are suitable for a very high viscosity of the pumped fluid. Furthermore the reciprocating pumps can be suitable for metering and dosing applications.
