AODD Series – Air Operated Double Diaphragm Pump

The AODD-Series pump design is there are only wetted parts that are dynamic: the two diaphragms, which are connected by Main common shaft, the two inlet valve balls and the two outlet valve balls. The diaphragms act as a separation membrane between the compressed Pnematic 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 from the operation and extends diaphragm life. This also allows the valve balls to open and close on the valve seats, which direct liquid flow. This simple design and operation makes it easy for the operator to find the correct pressures and flows to optimize its operation.
