摘要：

The results of the research which were employed in the systems design of the radial diffuser geometry of the multistage pump with respect to the internal flow pattern especially in the stator are presented in the paper. The contribution deals with the blade cuts shape of the radial diffuser, the course of the diffusion and the suppression of secondary flows in the radial diffuser passages. The areas with secondary flows are investigated on the basis of the CFD simulation. The good image of the influence of some characteristic parameters on the efficiency of the multistage pump with radial diffuser in bulk is obtained by the analysis of velocity and pressure fields in the diffuser.
