Plunger Pumps

Home -> Lecture Notes -> Fluid Mechanics -> Unit-V

Plunger pump consists of a heavy walled cylinder of small diameter contains a close-fitting plunger, which is merely an extension of the piston rod. At the limit of its stroke the plunger fills nearly all the space in the cylinder. Plunger pumps are single-acting and can discharge against a pressure of 1500 atm or more.

A plunger pump is differentiated from a piston in that a plunger moves past stationary packing, whereas a piston carries packing with it.
