The aim of the invention is to provide a device for axially delivering fluidic media such that said device exhibits a low-friction sealing, which does not generate any turbulences, between the stationary tubular hollow body and the rotating tubular delivering part, and with which sealants cannot be absorbed by the fluidic medium to be delivered. To these ends, the annular gaps between the tubular stationary hollow bodies and the rotating delivering part are provided with a magnetic fluid seal.
