The working principle of a Verderair double 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 rubberthermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm check valvebutterfly valves, flap valves, or any other form of shut-off valves to pump a fluid.

When the volume of a chamber of either type of pump is increased the diaphragm moving upthe pressure decreases, and fluid is drawn into the chamber [3].

When the chamber pressure later increases from decreased volume the diaphragm moving downthe fluid previously drawn in is forced out. This action is qodd to that of the cylinder in an internal combustion engine. Diaphragm Pumps deliver a hermetic seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant.

An elastomeric diaphragm can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods. pumpx

They do not leak, offer little friction, and can be constructed for low pressure sensitivity. With the right material consideration, diaphragms can seal over a wide range of pressures and temperatures without needing lubrication or maintenance.

Small mechanically activated diaphragm pumps are also used as air compressors and as a source of low-grade vacuum. Compared to other compressors, these pumps are quiet, cheap and, most importantly, have no moving parts in the airstream. This pmups them to be used without added lubrication in contact with the air, so the compressed air produced can be guaranteed clean.
