Diaphragm pump is a commonly used type of centrifugal pump, which works by moving the diaphragm up and down to achieve liquid suction and discharge. Below, we will provide a detailed introduction to the working principle of a diaphragm pump.

A diaphragm pump mainly consists of two pump heads and a diaphragm. Each pump head has a diaphragm, which forms a sealing chamber between the diaphragm and the pump head. There are inlet and outlet on both sides of the pump head, and the flow direction of the liquid is controlled by valves.
