Peristaltic Pumps Manufacturers

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. A rotor with a number of rollers, shoes or wipers is attached to the external circumference that compresses the flexible tube. As the rotor turns, the part of tube under compression closes 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 fluid, flow is induced to the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract. Peristaltic pumps are typically used to pump clean or sterile fluids or to pump aggressive fluids because the fluid cannot contaminate the pump. Some common applications include pumping aggressive chemicals, high solids slurries and other materials where isolation of the product from the environment, and the environment from the product, are critical.
