Abstract In order to investigate the effects of radial diffuser outlet pattern on exterior characteristic, pressure fluctuations and radial force of self-suction sprayer pump,the Shear Stress Transport turbulence model and SIMPLE algorithm were applied to simulate the unsteady flow of three different kinds of radial diffuser. The pressure fluctuations located at the outlet of radial diffuser and the radial force imposed on the volute were monitored. Time domains of the pressure fluctuations were analyzed and the pressure fluctuation amplitude and the radial force of were compared. The results show that with the exit area of radial diffuser inreasing, flow patterns located at the outlet of radial diffuser are improved and then the efficiency of the centrifugal pump is increased. At the same rate, with the exit area of radial diffuser increasing, the pressure fluctuation amplitude located at the outlet of radial diffuser is reduced. Besides, the damage of rotor-stator interaction between radial diffuser and second-stage impeller and the radial force imposed on the volute are reduced. The time-average radial force imposed on the wall is increased with the decreasing of the flow rate.
