The reciprocating pump engineering essay published: november 21, 2015 a pump is a mechanical device which helps to move fluids including liquids or gases it is basically a hydraulic machine which converts the mechanical energy to the hydraulic energy the fluid enters the pump through the suction valve and goes out threw the discharge. Positive displacement reciprocating pumps engineering essay published: november 21, reciprocating pumps have a fluid-handling portion, commonly called liquid end cylinder, which has: it must also have a driving mechanism to provide motion and force to the plunger or piston the most common driving mechanism is reciprocating steam engine. Fluid mechanics, the branch of science that deals with the study of fluids (liquids and gases) in a state of rest or motion is an important subject of civil, mechanical and chemical engineering. Pumps are in general classified as centrifugal pumps (or roto-dynamic pumps) and positive displacement pumps centrifugal pumps (roto-dynamic pumps) the centrifugal or roto-dynamic pump produce a head and a flow by increasing the velocity of the liquid through the machine with the help of the rotating vane impeller.
Discussion pankaj -posted on 14 oct 15 centrifugal pump has higher discharge rate than that of the reciprocating pump but reciprocating pumps are superior to centrifugal pumps for applications where very high pressures are needed to be developed at moderate discharge.
