How they work

Peristaltic pumps work using the process of peristalsis to pump products through a hose, in the same way that blood, food and oxygen are pumped around the body.

• The hose sits around a rotor which, when turning, compresses a segment of the hose almost flat.


• This compression is released as the rotor moves around the hose with the hose reinforcements causing it to spring back to its round shape, thus creating a partial vacuum refilling the hose.


• This compression creates a seal and, as the rotor turns, any product on the discharge side of the rotor is propelled forward and displaced from the pump.


• Combining this suction and discharge action results in a self-priming positive displacement pump.
