In a feed pump ( 2 ), guide vanes ( 9 ) fastened on a driven impeller ( 7 ) project into a recess ( 11 ) of a molding ( 8 ) annularly surrounding the impeller ( 7 ). The guide vanes ( 9 ) are located with a slight clearance opposite the wall of the recess ( 11 ). The guide vanes ( 9 ) can thereby have a particularly large surface. Moreover, a depositing of dirt in the radially outer region of the impeller ( 7 ) is avoided.
