Abstract
An impeller for a delivery pump in which profiled section (14) comprising webs (15) is located on the outer periphery of an impeller (4) for a feed pump (2) that is configured as a side channel pump. The webs (15) are arranged at an ascending incline, viewed in the rotational direction of the impeller (4) from the designated pressure side to the designated intake side. This permits flow losses between the radial external region of the impeller (4) and the housing parts (6, 7) of the feed pump (2) to be maintained at a particularly low level.
