20,000 PSI [1,375 BAR]Available in 1, 3, 4, 6, 8, 12 and 16 passage models, DSTI HPS Series rotary unions are capable of handling
pressures up to 20,000 PSI [1,375 BAR].
All HPS Series models feature a corrosion-resistant,
all-stainless steel construction for harsh marine and offshore environmental conditions and corrosive media
transfer.
Medium pressure housing connections and O-ring gland shaft connections come standard for
HPS Series models, suitable for common applications including umbilical hose reel systems and other high
pressure equipment. If needed, DSTI can make modifications to meet each application's specific requirements
including changes to the HPS Series mounting configuration, connections, sealing system, and housing or

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. The use of Water media with temperatures above 212° F (100° C) require alternative seal materials. Please consult with DSTI regarding your specific application requirements.
