Peristaltic Pumps

A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a number of "rollers", "shoes" or "wipers" attached to the external circumference compresses the flexible tube. As the rotor turns, the part of tube under compression closes (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution") fluid flow is induced to the pump. This process is called peristalsis and used in many biological systems such as the gastrointestinal tract.

Applications

Peristaltic pumps are typically used to pump clean/sterile or aggressive fluids, because cross contamination cannot occur. Some common applications include pumping IV fluids through an infusion device, aggressive chemicals, high solids slurries and other materials where isolation of the product from the environment, and the environment from the product, are critical.

A peristaltic can often be used in place of a double diaphragm pump.

We offer the ELRO Peristaltic pumps for industrial applications and the Autoclude tube pump for dosing applications.
