TUPWR algorithm was adopted for the pump turbine model, SFPUMP for feed pump system, SOVLV for minimal flow valve, and pressure node for calculating the discharge rate of the pump.

This paper introduces the structure and hydraulic design of the multiphase flow centrifugal pump, which draught sands from the riverbed and discharge the air of the suction pipe.

There exists a saddle type zone in the hydraulic moment curve of axial-flow pump blades which corresponds to the saddle zone of discharge-head characteristic curve of the pump.
