Abstract (en)
[origin: EP1522738A2] Spiral housing for a centrifugal pump has in the central region of the flow spiral a flow cross-section with a length (X) to width (Y) ratio of 1.5-2 and a ratio of first partial height (Y1) to second partial height (Y2) of 0.25-1. The first partial height is measured between the boundary of the flow cross-section lying furthest from the inlet (E) of the flow medium and parallel to the longitudinal axis of the inlet and the intersection (P) of the length and the width. The second partial height is measured between the intersection of the length and the width and the boundary (j) of the flow cross-section lying next to the flow medium inlet and parallel to the longitudinal axis of the inlet. The boundary (j) of the cross-section and the further boundary (h) lying next to the impeller of the pump are arranged at a right angle (alpha ) to each other.
