Rotary Unions for All Applications
Demanding Media – Liquid, Gaseous, Solid and Electric Current
Our rotary distributors enable the reliable transfer of a wide variety of media from stationary to rotating machine elements – regardless of whether they are liquid or gaseous or contain solids.
And regardless of the environment – whether indoor or outdoor, offshore, in high-temperature and high-pressure applications or underwater, as well as in a low-friction version. The list can be continued indefinitely…
Media
In addition to the standard applications in industry, where compressed air and hydraulic oil are the main media used, there are many other areas of application in which countless and almost unimaginable media have to be transferred.
At KONSTANDIN, many rotary distributors have already been developed and manufactured for such unusual media (see adjacent table).
And we look forward to many more new media, topics and challenges.
For this purpose, the sealing materials and the materials used for the components were selected to suit the media as well as the environment in which the rotary union is used.
Endless Combinations of Different Media
And not to be forgotten in this context is the possibility of transferring several different media – even at different pressures – through KONSTANDIN rotary distributors.
Our portfolio includes case examples of a wide variety of combinations:
- Compressed Air + Aerosol + CO₂
- Nitrogen + Vacuum
- Compressed Air + Peroxide
- …
Combination of Media + Transmission of Electric Current and Signals, Data, etc.
Furthermore, the rotary distributors for media can be combined with electrical components and slip ring assemblies in the desired configuration:
- Compressed air + lubricating grease in combination with a 12-pole electrical component for signal transmission/li>
- Compressed air + nitrogen-hydrogen mixture + trimethylaluminium + nitrogen in combination with a 5-pole electrical component for power supply + temperature sensor, designed for high temperatures up to 120°C
- Compressed air + water + shielding gas with a 43-pole electrical component for power supply + signal transmission + PROFINET, PE
