Centrifigal Pumps

The Centrifugal pumps are one of the most general components found in the fluid systems. In order to realize how a fluid system having a centrifugal pump operates, it is essential to understand the head and flow associations for a centrifugal pump.

Centrifugal pumps are sub-groups of dynamic axis symmetric work-absorbing turbo machinery. Centrifugal pumps are employed to transport liquids or fluids by the conversion of the rotational kinetic energy to the hydro-dynamics energy of the liquid flow. The rotational energy usually comes from an engine or electric motor or turbine. In the usual simple situation, the fluid enters the pump impeller all along or near to the rotating axis and is accelerated by the impeller, flowing radially outward to a diffuser or the volute chamber from where it exits.

The general uses involve sewage, water, petroleum and petrochemical pumping. The reverse task of the centrifugal pump is a water turbine converting potential energy of water pressure into the mechanical rotational energy.
