Diaphragm
Diaphragm pump technology (also known as a Membrane pump) is a positive displacement pump that uses a combination of reciprocating action of a 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.
At Sames, diaphragm pump are known under the name PMP or PDM.
