Abstract (en)
[origin: EP1972789A1] The above mentioned invention is related to a centrifugal pump, comprising an outer casing (1), an inner casing (2) contained in the outer casing (1), an impeller (5) rotatably supported around a central axis (24) within the inner casing, an inlet (3) concentrically arranged with respect to the impeller (5) as well as a tangential outlet (4), said outer casing (1) comprising a cup shaped part (13), a cover part (14) as well as a mounting arrangement by means of which said cover part (14) is mounted onto the cup shaped part (13), wherein the mounting arrangement comprises mounting means with co-acting spiral shapes associated with the cup shaped part (13) and of the cover part (14), in such a way that a mutual rotation of mounting means around the axis in one direction provides for a mutually fixed position of said parts, and a mutual rotation of mounting means around the axis in the opposite direction provides for a mutually detached position of said parts.
