Abstract (en)

[origin: EP0480261A1] The invention relates to a multi-part fluid guiding device composed of various materials for centrifugal pumps. When subjected to heat, differing expansion behaviour occurs depending on the materials used. Of the fitting positions (11, 12, 13) of the fluid guiding device effective in a radial direction only one fitting position ever applies depending on the particular temperature. In the cold operating state this is the fitting position (11) located on the smaller diameter, whereas in the warm operating position it is the fitting position (13) located on the larger diameter. <IMAGE>
