...52mm 3/8" Aluminum Diaphragm Pump Oil Change Chemical Resistant 26.5 L/Min Aluminum Diaphragm Pump Principle: As a result of air pressure acting on the entire surface of the diaphragm, the diaphragm is in a balanced condition while pumping. This measurably extends diaphragm life over that of mechanically air operated diaphragm pumps. Because compressed air is limited, the maximum pressure is also safely limited. This air operated diaphragm pump
