Peristaltic Pumps



What is a Peristaltic Pump?

Peristaltic pumps are 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. 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.


There are a number of 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
