Peristaltic Pumps
A peristaltic or roller pump is of the positive displacement type, where the fluid is contained within a flexible tube fitted inside a circular pump casing. 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 the 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. The process is called peristalsis and can be found in many biological systems such as the gastrointestinal tract.

Peristaltic Pumps (VISA)
Single channel industrial pump in space saving design with corrosion resistent pump head (cradle). Hose material is Pharmed or equivalent (can be sterilized). Available with fixed or variable speed drive for transport or metering of thin to viscous liquids in the production of food, cosmetics, pharmaceuticals and fine chemicals.
Peristaltic Pumps (VIP/SIC)
Single channel industrial pump in heavy duty rugged construction in close-coupled or classical long version.
Hose: textile reinforced thick walled rubber for pressures up to 15 bar. Excellent suction capability even with very viscous products, abrasion resistent, best suited for difficult products.
