[edit] Summary

Rotary peristaltic pump action

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.
