Oil rotary union HPS series

for water12-passagemedium-pressure

Description
DSTI 12-passage HPS Series rotary unions provide 12 independent flow passages with a specialized sealing system rated up to 20,000 PSI (1,375 BAR). They are designed for medium-pressure housing connections and all-stainless steel construction suitable for demanding industrial and offshore environments.

Design and construction
HPS 12-passage models include medium-pressure housing connections, O-ring gland shaft connections, and stainless steel housing and shaft. The design supports marine and offshore applications and can be adapted for specific installation requirements.

Customization
DSTI can modify mounting configuration, connection types, sealing systems, and housing or shaft dimensions to meet application-specific requirements, including alternative seal materials for elevated temperatures or special media.
