¨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 …

Classification of Centrifugal Pump Centrifugal pumps are classified in several ways. Pumps may be classified: • in terms of energy conversions (volute type and diffuser vane ring type); • in terms of fluid flow through the pump (radial, mixed flow and axial flow); • as either single stage or multistage i.e. in terms of number of stages; • according to …
