Centrifugal pumps are used to transport fluids by the conversion of rotational energy to the hydro dynamic energy of the liquid flow. The rotational energy comes from an engine or electric motor or turbine. In most cases, the fluid enters the pump along or near to the rotating axis and is accelerated by the impeller, flowing radially outward to its point of exit.
Centrifugal pumps are unique because they can provide high flow rates and the flow rate can be controlled with a simple valve placed into the discharge piping without causing excessive pressure buildup in the piping or requiring a pressure relief valve. Therefore, centrifugal pumps can cover a very wide range of liquid pumping applications and are among the most popular liquid handling pump used.
