Double Diaphragm Pumps

AODD pumps require no electricity and can be used in enclosed spaces or underground, which means they can operate safely and reliably in explosive environments when equipped with the proper provisions.lso known as a Membrane pump that uses a combination of the reciprocating action of a rubber, thermoplastic or PTFE and suitable valves on either side of the body (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.Single acting pumps incorporate one diaphragm and one set of valves, and are characteristic of mechanical drive pumps. Double acting pumps, also known as double diaphragm pumps, incorporate two diaphragms and two sets of valves. Air-operated diaphragm pumps are characteristically double-acting.
