Fluid Pumps: Classification and Types

Classification of fluid or hydraulic pumps is based on fluid flow pattern through pumps and fluid supplied by pumps. Pumps can be classified as intermittent flow Positive Displacement Pumps and continuous flow Roto-Dynamic or Turbo Pumps. Read more on...

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...
