Abstract

A centrifugal pump capable of being coupled to a drive motor, where the pump has an impeller (3) for radial direction of flow and having a discharge edge (13) at its outer diameter, and where the pump has a radially split pump casing (15) and is provided with at least one shaft seal (2). The impeller (3), for absorption of the forces acting on the impeller (3), is supported in a bearing device advantageously consisting of two axially adjacent bearings (1, 1'), where the width of the bearings or their respective bearing raceways (12, 12'; 14, 14') forms a characteristic distance a. A centre point (4) on the discharge edge (13) of the impeller (3) has, seen axially, a position which is at a distance b from another centre point between the bearings (1, 1') and in the direction of or from the inlet end (21) of the pump, where b </= 2a.
