Peristaltic pumps

What is a peristaltic pump?

A peristaltic pump, also called a tubing pump, moves liquid by rotating compression of a flexible tube. Rollers or shoes locally squeeze the tube shut, pushing the liquid forward in one direction. As soon as the tube relaxes, it fills with liquid again.

The big advantage of this contact-free pumping principle is that the liquid only comes into contact with the tubing and not with the mechanical parts of the pump. This makes peristaltic pumps particularly suitable for sterile, corrosive or sensitive liquids, and for applications where cross-contamination or contamination must be prevented.
