Centrifugal Pump Start-up Procedure - EnggCyclopedia

Centrifugal pumps. Centrifugal pumps convert energy of an electric motor or turbine into velocity or kinetic energy and then into pressure energy of the fluid being pumped. The energy changes occur around two main parts of the pump, impeller and volute or diffuser. Pump impeller is the rotating part that converts driver energy into the kinetic energy.
