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 ).
