Abstract

In a feed pump (2) designed as a side channel pump, with an impeller (5) rotating in a pump casing (3) and having blade chambers (12, 13), the blade chambers (12 13) have an inflow region (16, 17), the profile of which is designed asymmetrically to that of an outflow region (18, 19). The feed pump (2) can thereby be adapted to an intended characteristic simply by exchanging or reversing the rotation of the impeller (5).
