ABSTRACT:
A vertical centrifugal pump unit, in particular for wet installation in a closed container, including an intermediate pipe (17) which surrounds the shaft (3) of the pump unit and is arranged between the housing (11) of the centrifugal pump (12) and a bracket (5) which carries the electric motor (1) of the unit. The pump unit preferably is fastened in particular to a horizontal flat part (19) arranged beneath the flange (6) of the bracket (5), especially the cover of a container. Production is simplified and it is possible to readily adapt the intermediate pipe to different sizes by designing the intermediate pipe (17) without a flange or other enlargements on its end faces, and pressing the end faces against the bracket (5) and the pump housing (11) using screw connections (18, 20) distributed uniformly around the circumference. The bracket (5) and the flat part (19) arranged beneath the bracket are joined together by the screw connections (18, 20).
