Abstract (en)
[origin: EP0870928A1] The invention relates to a circulating centrifugal pump for a dishwasher with a pump casing with an axial inlet opening and a radial outlet opening, and with a pump chamber expanding in a spiral shape with a spur (17), and in which there is rotarily mounted a round pump rotor (20) with a predetermined distance from the spur (17), and whose vanes (16) are disposed on a support disc (12). A noticeable reduction in noise during operation can be achieved in a simple way in that the diameter of the ends of the vanes (16) is reduced relative to the diameter of the support disc (12), and the radial spacing (b) of the ends of the vanes from the spur is correspondingly enlarged compared to the radial spacing (a) of the support disc from the spur. <IMAGE>
