Abstract
In a feed pump (), guide vanes () fastened on a driven impeller () project into a recess () of a molding () annularly surrounding the impeller (). The guide vanes () are located with a slight clearance opposite the wall of the recess (). The guide vanes () can thereby have a particularly large surface. Moreover, a depositing of dirt in the radially outer region of the impeller () is avoided.
