What are positive displacement pumps and how do they work?

Positive displacement pumps are special pumps that transport liquids or gases by displacement. In contrast to other types of pumps, such as centrifugal pumps, their mode of operation is based on the principle of displacing the volume of elements.

Functionality of positive displacement pumps

The basic function of a positive displacement pump is to contain a certain amount of the medium to be pumped – be it liquid or gas – in a chamber and to move it from an inlet to an outlet by mechanical movement (e.g. turning or pushing). This process is achieved by various mechanisms, such as pistons, diaphragms, screws or gears. These mechanisms periodically increase the volume in the chamber (to draw in the medium) and then reduce it (to displace it). When the displacement is achieved by a plunger, the pumps are also called plunger pumps.

  1. Suction phase: The displacer (e.g. a piston or plunger) in the pump retracts, creating a vacuum and drawing the medium through the inlet into the chamber.
  2. Displacement phase: The displacer moves forwards, reducing the volume of the chamber and increasing the pressure inside.
  3. Discharge phase: The increased pressure forces the medium out of the chamber through an outlet and into the pipe system or a container.
  4. Return to initial state: The displacer returns to its starting position to repeat the cycle.

Areas of application for positive displacement pumps

Due to their efficiency and precision, positive displacement pumps are indispensable in a variety of industries. Some of the most common areas of application are:

  • Industrial cleaning
  • Mining
  • Shipyards
  • Construction
  • chemical industry
  • Aquaculture
  • Oil and gas industry
  • Process technology

Positive displacement pumps – different types

Positive displacement pumps are a class of pumps that displace liquids or gases by periodically increasing and decreasing the volume of an enclosed space. They are classified into

  • oscillating (e.g. piston or diaphragm pumps)
  • rotating (e.g. gear or rotary lobe pumps)
  • and a combination (e.g. radial piston pumps).

A very well-known type of positive displacement pump is the plunger pump. Plunger pumps use a piston (plunger) that moves back and forth in a cylinder. The reciprocating motion of the plunger, which is often made of ceramic, draws liquid into the cylinder, which is then expelled by the movement of the plunger towards an outlet valve, compressing the liquid by reducing the volume of the cylinder. Plunger pumps are not used for gases, as these generally have a larger free space.
