DescriptionDSTI 16-passage HPS Series rotary unions feature 16 independent flow passages and a specialized sealing system capable of handling pressures up to 20,000 PSI [1,375 BAR]. HPS 16-passage models include medium pressure housing connections, O-ring gland shaft connections, and an all-stainless steel construction intended for harsh marine and offshore environments.
CustomizationHPS Series units can be modified for application-specific requirements including changes to mounting configuration, connections, sealing system, and housing or shaft dimensions.

NotesAll values listed under Technical Specifications depend on a combination of application parameters. Operational life is dependent on rotational speed and duty cycle. Applications with temperatures above 220° F (105° C) require alternative seal materials. The use of water media with temperatures above 212° F (100° C) requires alternative seal materials.
