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

Its working principle is to repeatedly squeeze the highly elastic hose to make the contents in the hose move in a certain direction. Its flow rate is determined by the diameter of the tube and the compression speed. It is often used in systems such as liquid chromatography and perfusion. According to its specific use, it can be divided into speed-regulated peristaltic pumps, flow-type peristaltic pumps and distribution-type peristaltic pumps.
