¨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 …

Positive displacement pumps operate on a different principle than centrifugal pumps. Positive displacement pumps physically entrap a quantity of liquid at the suction of the pump and push that quantity out the discharge of the pump. A positive displacement pump is one in which a definite volume of liquid is delivered for each cycle of pump operation. This volume is …
