Peristalic Pumps

Peristalic 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", "wipers", or "lobes" attached to the external circumference of the rotor compresses the flexible tube. As the rotor turns, the part of the tube under compression is pinched closed (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" or "resilience") fluid flow is induced to the pump.

Murhopye Peristaltic Pumps are specially designed to provide accurate and reproducible flow rates for laboratory and industrial applications. These are self priming pumps and are ideally suited for pumping corrosive liquids and sterilized medium, acids, alkali and antifoam agents under aseptic conditions. These pumps are available in single or multichannel configuration. A variety of combinations of rotor, tubing and speeds are offered to cover diverse applications / flowrates. These pumps may run continuously, or they may be indexed through partial revolutions to deliver smaller amounts of fluid.
