Abstract (en)
[origin: EP0733808A1] The pump has one or more running wheels in its casing and flow guide parts in the region of the through-flow apertures. These parts are in the form of wall projections (6), encompassing two surfaces (A,B) running in the flow direction and merging with the circumferential surface of a through flow aperture (5). The two surfaces (A,B) enclose an angle which is such that the side lines (a,b) of the two surfaces are in a ratio of a/b not more than (1). The side lines, in connection with a part of the circumference of the through-flow aperture, enclose another wall surface (C).
