Abstract

A centrifugal pump having a barrel casing and at least one stage casing therein includes a transition from the last stage casing to the pressure connector of the barrel casing in the form of a spiral flow space. The contour of the spiral flow space is formed by a contour of the last stage casing, a contour of a cover which closes the barrel casing on an end face, and an inner contour of the barrel casing.
