Abstract (en)

[origin: WO0248551A1] The invention relates to a feed pump (2) that is configured as a side-channel pump with a plurality of identically designed feed chambers (6, 7) with outlet channels (22, 23) that are disposed opposite one another, thereby eliminating the radial forces acting upon the impeller (4) of the feed pump (2). The feed pump (2) according to the invention is especially wear-free and has a very high degree of efficiency.
