Q – What is a centrifugal pump and how does it work?
A – Centrifugal pumps have been relied upon as an industry workhorse since the 17th century and are the most commonly used type of pump for the transfer of liquids.
A centrifugal pump operates through a rotating impeller within a casing that is usually driven by an electric motor or petrol / diesel engine. The centrifugal pump converts rotational kinetic energy from the driver to the hydrodynamic energy of the fluid flow.
Fluid enters through the inlet of the pump and into the eye of the impeller. As the impeller rotates, the liquid accelerates radially between the vanes, gaining both velocity and pressure until it exits at the outside diameter where it is directed to the pump outlet by the volute casing. As the liquid is discharged from the casing, the flow velocity is reduced, and discharge pressure increased.
Centrifugal pumps are the ideal solution for any transfer of liquids especially when higher flow-rates are requires or pumping solids laden liquids.
