ABSTRACT:
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.
