As the research object to a aero fuel centrifugal pump with inlet flow ejector, this paper research the numerical simulation of the centrifugal pump. The simulation’s accuracy by Pumplinx was validated by comparing the simulation datas with test datas. Studies have shown that this centrifugal pump’s head, efficiency and cavitation characteristics curve of numerical simulation meet the test data. Then the inner flow characteristics of the model is calculated by analysing the pressure of middle axial and middle radial area. Pressure of inner flow is steady, and could make high pressure at high efficiency at the small flow states; Meanwhile, the ejector can influenced the inner flow performance.
