What is peristaltic pump?

Peristaltic, tube or hose pump is a type of positive displacement pump that transports the liquid through the tube by a series of rollers, that squeeze it against the pump housing, in a similar way that we swallow food.

How does a peristalsis pump work?

A peristaltic pump also referred to as a hose or tube pump works using positive displacement. Fluid is fed through the tubing by rollers that rotate squeezing a flexible tube against the pump housing. As the roller moves over the tubing, it expands and creates a vacuum to allow more fluid to enter.

What are peristaltic pumps good for?

Peristaltic pumps are typically used to pump clean/sterile or highly reactive fluids without exposing those fluids to contamination from exposed pump components.
