Guide ring for an impeller pump and impeller pump

摘要

A guide ring for a heated impeller pump for dish washers may include a base body in the type of a circumferential ring having a central longitudinal axis and which is configured for arrangement in a pump chamber of the impeller pump. At least one blade may be arranged on a radial outer surface of the base body, which protrudes outwards and which extends longitudinally along the base body over at least a part of the periphery thereof and which has a pitch in relation to the central longitudinal axis. At least on one side of the blade, a protrusion or a thickening may be provided on the outer edge thereof. The latter can form a channel configured to remove air bubbles from the pump chamber.
