Centrifugal and Positive Displacement Pumps

Centrifugal pumps basically consist of a stationary pump casing and an impeller mounted on arotating shaft. The pump casing provides a pressure boundary for the pump and containschannels to properly direct the suction and discharge flow. The pump casing has suction anddischarge penetrations for the main flow path of the pump and normally has small drain and ventfittings to remove gases trapped in the pump casing or to drain the pump

Centrifugal vs. Positive Displacement Pump Pump Types ...

Both centrifugal and positive displacement pumps transfer water from an inlet point to an outlet point at a controlled degree of force and quantity. However, the mechanisms they use are different. Positive displacement pumps draw fluid into a cavity, or displace the fluid, and then force the fluid out of the cavity through suction.

17/10/2016  You will notice in the flow rate chart how the centrifugal pump loses flow as the viscosity goes up but the Positive Displacement pump’s flow actually increases. This is because the higher viscosity liquids fill the clearances of the pump causing a higher volumetric efficiency. Remember, this chart shows only the effect of viscosity on the pump flow; when there is a viscosity change there is ...

Centrifugal pumps are by far the most commonly used pump type. In a centrifugal pump, fluids are transported by means of rotational energy which is typically created by an engine or an electric motor. The other main pump type is the positive displacement pump. In positive displacement pumps, the flow depends on the pump’s speed. These pumps are often better suited to pump thicker liquids ...
