Types of Reciprocating Positive Displacement Pumps: Diaphragm Pump

Diaphragm Pumps have a diaphragm as the reciprocating part. The reciprocation of this diaphragm produces the pumping action of the diaphragm pump. The diaphragm can be actuated by liquid or air. Accordingly pumps are called as hydraulically operated or air operated diaphragm pumps.
