Brochures & Manuals


Graco air-operated double diaphragm (AODD) pumps use compressed air as a power source. The compressed air is shifted from one chamber and then to the other side by a linked shaft. This movement allows the chambrs to move simultaneously. This back-and-forth motion forces liquid out of one chamber and into the discharge piping while simultaneously filling the other chamber with liquid. These pumps use reciprocating elastomeric diaphragms and check valves to pump fluid. The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet.
