This air-operated double diaphragm pump features two symmetrical pump chambers equipped with diaphragms connected by a center couplet stem. Compressed air enters through the pump inlet valve, flowing into one cavity to push the diaphragm movement while gases are emitted from the other cavity. Upon reaching the destination, gas distribution components automatically redirect compressed air into the opposite chamber, pushing the diaphragm in the reverse direction. This creates continuous synchronized reciprocating movement between both diaphragms.
