  • Centrifugal pump Wikipedia

    A common application of the multistage centrifugal pump is the boiler feedwater pump. For example, a 350 MW unit would require two feedpumps in parallel. Each feedpump is a multistage centrifugal pump producing 150 l/s at 21 MPa. All energy transferred to the fluid is derived from the mechanical energy driving the impeller.
