A peristaltic pump is a positive-displacement pump in which a motor pinches advancing portions of a flexible tube to propel a fluid within the tube. The pump isolates the fluid from the machinery, which is important if the fluid is abrasive or must remain sterile. Robots have been designed that use peristalsis to achieve locomotion, as the earthworm uses it. WebApr 9, 2024 · Peristalsis is derived from the Greek term peristaltikos, which means to clutch and compress. It is a known fact that a peristaltic wave propagating along the pliable walls of a tube/channel can push small particles suspended in fluid even without an external pressure gradient. The reproductive system of males and females is a good example.
