Air-operated Double Diaphragm (AODD) pump is a most common type of diaphragm pump. The operation of the air-operated pump may be carried out with compressed air. It has two pumping chambers with two diaphragms.
AODD pump has a discharge check valve, a diaphragm and a suction check valve for each pumping chamber. The air supply moves from one chamber to the second assembly chamber through an air distribution system that may install inside the pump.
The systematic operation of air transfer from one assembly chamber to other chamber causes liquid from one chamber to flow down the drainpipe by filling the other chamber with liquid. As a result, the pump has a pulsation in the discharge flow. This pulsating flow may reduce by using a pulsation damper in the delivery pipe.
