A feed unit for a fuel pup includes a rotor eccentrically mounted in a pump chamber, and a plurality of grooves disposed on the periphery of the rotor. The grooves receive a plurality of sealing bodies which extend from within the grooves to an annular wall of the pump chamber embodied as a curved track. A gap is defined between the rotor and the curved track and is subdivided into gap spaces that are sealed from each other by the sealing bodies, which are configured as elastic spring elements.
