Beschreibung
Zusammenfassung:	A multimedia-compatible rotary union for transferring different fluid media, having different viscosities, from a stationary machine part to a rotating machine part includes a stationary housing part having a working space, a rotor having a fluid channel and a fluidic connection to the working space, a mechanical seal between the stationary housing part and the rotor, including a rotor seal ring that rotates with the rotor, and an axially movable seal ring assembly having a stator seal ring, wherein the stationary housing part includes first and second media inlet channels that introduce fluid media into the stationary housing part, open into the working space, and allow fluid media under pressurization into the rotary union, and wherein the mechanical seal has a first balance ratio when the first media inlet channel is pressurized with medium and a second balance ratio when the second media inlet channel is pressurized with medium.
