Abstract

A side-channel pump includes guide means for the radial and/or axial guidance of an impeller, the guide means being arranged in the radially outer area of the impeller. The guide means include guide surfaces arranged on the impeller at an intended angle to the ends of the impeller. The frictional losses of the side-channel pump are thereby kept particularly low.
