“Closed Seal” Designs – when media is present during rotation
“Closed Seal”: As the name suggests, the seal rings of this rotary union remain closed with or without coolant pressure.
Pop-Off Designs – when rotation without media is possible
When depressurised, the seal rings separate from each other, thereby creating a small gap.
AutoSense Designs – when both coolant and pressurised dry air are used interchangeably
AutoSense® – self-adjusting: These rotary unions represent the pinnacle of all mechanical seal technologies, combining the best of the “Closed Seal,” Pop-Off®, and “controlled leakage” technologies
Compact bearingless cartridge models
Bearingless rotary union cartridges are compact rotary unions for the smallest of installation spaces. These single-passage versions can be equipped with almost any sealing technology. Full-media flow.
