Abstract (en)
[origin: DE19906130A1] The invention relates to a delivery pump (2) which is configured as a side channel pump, comprising a driven impeller (4) which rotates in a housing (3). A liquid to be delivered is conveyed to guide blades (6) in the impeller (4) from the radial inner area. The impeller (4) has a groove (17) for this purpose, said groove being adjacent to the guide blades (6). As a result, the delivery pump (2) has a particularly high degree of efficiency.
