In the two symmetrical working chambers of the double-diaphragm pump, each is equipped with a flexible diaphragm. The connecting rod integrates the two diaphragms. After the compressed air enters the intermediate body from the air inlet connector of the pump, the two working chambers are pushed The diaphragm, drive connecting rod diaphragm synchronized movement. At the same time, the gas in the other working chamber exits the pump from the back of its diaphragm. When the piston reaches the end of the stroke, the valve mechanism automatically introduces compressed air into the other working chamber to push the diaphragm pump in the opposite direction, thus forming a synchronous reciprocating motion of the two diaphragms. Each working chamber is provided with two one-way ball valves. The reciprocating motion of the diaphragm causes changes in the volume of the working chamber, forcing the two one-way ball valves to alternately open and close so that the liquid is continuously drawn in and discharged.

The most obvious difference from other pneumatic double diaphragm pumps is the valve configuration. Pneumatic double diaphragm pump valve structure to eliminate the traditional "O" ring and cylindrical valve configuration valve. Using three-way pilot, eliminating the valve dead point and pump down phenomenon. Proper and reliable commutation signals are provided to avoid downtime and faster commutation to give the pump greater flow, providing transport performance for smaller pulses and more stable flow.

Pneumatic Double Diaphragm Pumps Simple, highly reliable air reversing valves ensure costly downtime without downtime. All air valve components can be replaced without disassembling the fluid section. Aluminum parts are specially treated to prevent corrosion caused by unclean air. The plastic-made slide block in the reversing valve is durable and hard to be damaged. Lubrication is not required to ensure smooth air passage and flexible direction.
