A method is presented which has been developed for determining the hydrodynamic mass of the impeller stage of the rotor which accounts for the three dimensional geometry of the impellers and the effects of the fluid velocity. By using this method, more accurate calculations of resonant frequencies of the rotor and hence the seal forces can be made. In comparison with previous approaches, two main features have been included: (1) an accurate representation of the shape of the impeller and the pump geometry; (2) the effects of the velocity of the fluid.
