The centrifugal or roto-dynamic pump produce a head and a flow by increasing the velocity of the liquid through the machine with the help of the rotating vane impeller.

Selecting between Centrifugal Pumps and Positive Displacement Pumps

Centrifugal pumps include radial, axial and mixed flow units. A positive displacement pump operates by alternating filling a cavity and then displacing a given volume of liquid.

A positive displacement pump delivers a constant volume of liquid for each cycle independent of discharge pressure or head. The two types of pumps behave very differently regarding pressure head and flow rate:. Liquids with high viscosity fills the clearances of Positive Displacement Pumps causing higher volumetric efficiencies and Positive Displacement Pumps are better suited for higher viscosity applications. A Centrifugal Pump becomes very inefficient at even modest viscosity.
