Peristaltic pumps

peristaltic pump

A peristaltic pump is a type of positive displacement pump.

The fluid is contained in a tube inside the circular pump casing, pushed by rotors which squeeze the hose flat (as shown below). In front of the roller, pressure builds up and because of the hose’s elasticity a vacuum builds up behind the roller. The pressure pushes the fluid out of the hose and the vacuum sucks the new fluid in.

Peristaltic pumps are used in a wide range of industries and applications such as food, mining, chemical, fishing and agriculture as well as on and off shore, in anaerobic digestion / biogas and in the production of concrete and paint.

The benefits of using peristaltic pumps 

  • The liquid never coming into contact with any moving part therefore totally removing the risk of contamination

  • Very low energy usage

  • Few wear parts mean lower maintenance costs, saving you money

  • The ability to run dry

  • The ability to handle a wide variety of materials including solids
