Abstract
The follow-up guide wheels of a multistage centrifugal pump define flow paths whose cross-sectional area increases exclusively in the axial direction of the respective stages, or axially and radially inwardly, to thus allow for a reduction of the outer diameters of the guide wheels without reducing the efficiency of the pump.
