HPS Series 8-Passage Rotary Unions & Joints
DSTI 8-passage HPS Series rotary unions feature eight independent flow passages and a specialized sealing system capable of handling pressures up to 20,000 PSI [1,375 BAR].
HPS 8-passage models feature standard medium pressure housing connections, O-ring gland shaft connections, and an all-stainless steel construction for harsh marine and offshore environments.
If needed, DSTI can make modifications to meet application-specific requirements including changes to the HPS Series mounting configuration, connections, sealing system, and housing or shaft dimensions. See options.

*Minimum torque required to rotate based on zero pressure with oil/hydraulic media. Required torque to rotate may be greater when using other media types or dry running. For specific torque requirements, please contact DSTI to discuss your application.
All values listed under Technical Specifications are dependent on a combination of all application parameters. Please note operational life is dependent upon both rotational speed and duty cycle. Contact DSTI if your application requires operating close to the maximum rotational speed with a continuous duty cycle. Applications with temperatures above 220° F (105° C) require alternative seal materials. Please consult with DSTI regarding your specific application requirements.
