¨Pumps are divided into two fundamental types based on the manner in which they transmit energy to the pumped media: kinetic or positive displacement. Kinetic Displacement Pumps, a centrifugal force of the rotating element, called an impeller, “impels” kinetic energy to the fluid, moving the fluid from pump suction to the discharge. Positive Displacement Pumps use the reciprocating action of …

Pumps Reference Guide 3rd edition by Gordon S. Bolegoh. Industrialization imposed an ever-increasing demand for moving liquids from one location to another far more practically than by gravity. In order to motivate the fluid to move through the pipes and channels, energy has to be imparted to the liquid. The energy, usually mechanical, provided by a prime mover is transferred …

Centrifugal pump Components vary in design and construction from simple pumps with relatively few parts to extremely complicated pumps with hundreds of individual parts. Some of the most common components found in centrifugal pumps are wearing rings, stuffing boxes, packing, and lantern rings. Wearing Rings Centrifugal pumps contain rotating impellers within stationary pump casings. To allow the impeller to rotate …
