In a feed pump designed as a side-channel pump, a blade chamber of an impeller has a contour which is formed by a radius and in which, as seen from the contour, the origin of the radius is located behind a center line of the blade chamber. A circulation flow thereby passes into the blade chamber with particularly low turbulences. The feed pump has particularly high efficiency as a result.

Side channel pump

A feed pump includes an impeller with two rings of guide blades delimiting blade chambers. The rings of guide blades concentrically surrounding one another and have different angular intervals between guide blades. The angular intervals between the guide blades of each ring vary within a range of values and ranges of values of each ring of guide blades is different to avoid the additions of noise emissions the feed pump consequently has noises which cause particularly little disturbance.
