Peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a number of "rollers", "shoes", "wipers", or "lobes" attached to the external circumference of the rotor compresses the flexible tube. As the rotor turns, the part of the tube under compression is pinched closed (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution" or "resilience") fluid flow is induced to the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract. Typically, there will be two or more rollers, or wipers, occluding the tube, trapping between them a body of fluid. The body of fluid is then transported, at ambient pressure, toward the pump outlet. Peristaltic pumps may run continuously, or they may be indexed through partial revolutions to deliver smaller amounts of fluid.   

Peristaltic pump head with many models to fit the pump, so that control the flow of the liquid.
 
1. DG serials head
Features: DG series are designed for small flow and multi-channel transmission, easy to replace and fix tubing. Self adapting spring adjusts pressing gap automatically according to tubing. The rollers are made of 304 stainless steel. A whole pump head consists of three parts: frame, roller device and cartridge. According to the numbers of channel, there are DG1, DG2, DG4, DG8,DG12 ,DG16,DG24series.
