“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.
