ABSTRACT:
In a centrifugal pump, particularly for conveying tailing water in dressing plants for minerals such as coal, as for flue gas desulfuration systems or the like, a spiral housing is clamped between two retainer plates which externally connect to parallel wear walls without being bolted thereto. The retainer plates are designed as a two-piece, externally screw-connected enclosure for a hydraulics portion of the pump. The spiral housing is connected with the external screw-connection over retaining lugs. The enclosure parts are designed as flat retainer plates having a smooth clamping face for the spiral housing and the wear walls, and exhibit feet that have been welded on.
