Abstract

The invention relates to a pump module (2) comprising a housing part (4) with precisely determined force introduction points (25) in relation to adjacent components. Supporting elements (24, 27) and a groove (26) are located between the force introduction points (25) and a disc element (20) that comprises a partially annular channel (10). Forces that are introduced into the housing parts (4) thus lead to negligible deformations in the areas of said housing parts (4) that are adjacent to the impeller.
