摘要

The fluid flow machine (1) has a housing (20) with a fluid guiding housing (21,22) and a bearing housing (23) that is connected with the fluid guiding housing. Impellers (11,31) are mounted in the fluid guiding housing over a central impeller shaft in a rotating manner, where the impeller shaft has impeller blade (11a). The guiding blade bases (13b,33b) is formed integrally and extends symmetrically with an inner contour of an impeller covers (21a,22a).
