Air Diaphragm Pumps

 An Air Diaphragm Pumps is a type of positive displacement pump that uses compressed air as a power source. The compressed air is shifted from one chamber to the other, by a linked shaft that allows the chambers to move simultaneously.

Diaphragm pumps use reciprocating elastomeric diaphragms and check valves to pump fluid. The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet.
