Diaphragm Pump
 

 

Diaphragm pump is an air-operated positive displacement pump. It displaces fluid from one of its two liquid chambers upon each stroke completion. There are a few wetted parts (parts contact with fluid) which are dynamic: The two diaphragms which are connected by a common shaft, the two inlet valve balls and the two discharge valve balls.

 

The diaphragms act as a separation membrane between the compressed air supply and the liquid. Driving the diaphragms with compressed air instead of the shaft balances the load on the diaphragm which removes mechanical stress and therefore extends diaphragm life. The valve balls open and close on the valve seats to direct liquid flow.
