Diaphragm pump

A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm(check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.CFD animation of a diaphragm pumpDouble acting membrane pump on oil tanker deckMembrane pump animation A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm(check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.
