A peristaltic pump is a liquid delivery device that can control the flow rate. It consists of three parts: a peristaltic pump drive, a peristaltic pump pump head, and a peristaltic pump hose.

Its working principle is to repeatedly squeeze the highly elastic hose to make the contents of the hose move in a certain direction. The flow rate is determined by the diameter and compression speed of the tube. It is commonly used in liquid chromatography, perfusion and other systems.

According to its specific purpose, it can be divided into speed-regulating peristaltic pumps, flow-type peristaltic pumps, and distribution-type peristaltic pumps.
