Diaphragm pump, also known as control pump, is the main type of actuator, by accepting the control signal output of the control unit, with the help of dynamic operation to change the fluid flow. Diaphragm pump is generally composed of actuator and valve. If according to the power used by its actuator, the diaphragm pump can be divided into three kinds: pneumatic, electric and hydraulic, that is, pneumatic diaphragm pump with compressed air as the power source.
