What is Positive Displacement Pump – Definition, Types and Working?

Positive displacement pump (PDP) is a type of pump in which a moving fluid is captured in a cavity and then discharges that fixed amount of fluid. The displacement of fluid takes place by some parts like plunger, piston, diaphragm etc. some of these pumps have expanding cavity at the suction side and a decreasing […]

Reciprocating Pump – Main Parts, Types, Working, Advantages, Disadvantages with Application

What is Reciprocating Pump? Reciprocating pump is a hydraulic machine which converts the mechanical energy into hydraulic energy. It does this work by sucking liquid into a cylinder containing a reciprocating piston which exerts a thrust force on the liquid and increases its hydraulic energy ( pressure energy of liquid). It is a type of

Centrifugal Pump – Working Principle, Main Parts with Application

Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy (i.e. pressure energy) by the use of centrifugal force acting on the fluid. The flow of liquid takes place in radial outward direction which is reverse of the inward radial flow reaction turbine. It is used in different areas where fluid is
