high-pressure rotary union / hydrostatic

The Rotation speed up to 100,000 rpm is possible.
230 bar pressure is possible.
Ceramic contact seals enable long service life.
NO leakage when the flow of the medium stops.
Can be used for dry operation as well.
Various connection variations are available.

Function and Design

The Rotodisk S series are axial rotary unions with hydro-statically released contact seals and an automatic alignment compensation system and are single channeled. This enables the contact seals to have perfect full surface contact always.
The influence of the pressure of the medium on the moment of friction negligible is due to the hydro-static release. The wear is minimized due to a very small amount of friction because of the combinations of this system.
The advantage of this technology is that Rotodisk S, at the simultaneous high pressure of 80 bar and the very high operating speeds of 60,000 rpm , and can be operated reliably.
