Air operated diaphragms pumps (also known as pneumatic diaphragm pumps, AODD pumps, AOD pumps) are used for endless applications in mining, industrial and general plant service. Air operated diaphragm pumps are especially used where electricity isn’t available, or in explosive or flammable areas. They are also used for chemical transfer, de-watering underground coal mines, food manufacturing or where the liquid being pumped has a high solids content or high viscosity.

Air operated diaphragm pumps are a type of reciprocating diaphragm pump which contains two diaphragms driven by compressed air. Air section with shuttle valve applies air alternately to the two diaphragms, each diaphragm has a set of check/ball valves.

The premier manufacturer of air operated diaphragm pumps is Graco with which All Pumps has had a long association.
