Peristaltic

Peristaltic Positive Displacement Pumps. These positive displacement pumps move fluids through a flexible tube fitted inside the pump casing. A turning rotor/cam with rollers attached to its outer circumference, compresses the tube, forcing the fluid to move through it. When the rotor/cam lifts the rollers from the tube, it re-opens, and fluid flow is induced to the pump. This process is called peristalsis. The tube prevents fluids from contaminating or being contaminated by the pump.
