Abstract
The present invention relates to a separation type pneumatic dual partition membrane pump, which comprises a pump body and an external pneumatic control valve which is separately installed. Through the operation of the external pneumatic control valve, the main shaft of the pump body and the valve rod of the external pneumatic control valve are reciprocally moved, and the two partition membranes respectively generate stretch and compress motions for changing the volume of each liquid room in the pump body so as to perform the pump stroke and the liquid suction stroke to the liquid.
