In the two symmetrical working chambers of the pump, an elastic diaphragm is installed respectively, and the connecting rod connects the two diaphragms into one. After compressed air enters the air distribution valve from the air inlet joint of the pump, the diaphragm in the two working chambers is pushed to move, driving the two diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged out of the pump from the back of its diaphragm. Once it reaches the end of the stroke, the valve distribution mechanism automatically introduces the compressed air into the other working chamber to push the diaphragm to move in the opposite direction, thus forming the synchronous reciprocating movement of the two diaphragms. Each working chamber is also provided with two one-way ball valves. The reciprocating motion of the diaphragm changes the volume of the working chamber, forcing the two one-way ball valves to open and close alternately, so as to continuously suck and discharge the liquid.
