GPS Series 10-Passage Rotary Unions & Joints
The 10-passage, GPS Series rotary unions feature specialized sealing technology suitable for vacuum and bidirectional pressures and ten independent flow passages capable of transferring different media types simultaneously.
The stainless steel construction is suitable for hydraulic, pneumatic, coolant, water, and other corrosive media types. Carbon steel models are available for applications that do not require water or corrosive media transfer (see GP Series).
GPS 10-passage models come standard with NPT threaded connections on the sides of the shaft and housing. Optional O-ring face seal glands are available (must be specified when ordering).
Need to combine fluid with electrical power, signal and/or data transfer? No problem. The GPS Series rotary unions are designed to integrate directly with our standard electrical slip rings. See options.

*Minimum torque required to rotate based on zero pressure with Oil/Hydraulic media (or Air/Gas media for SPS Series). 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.
- 1Standard, Radial NPT Connections (Plugged If Axial Connection Type Is Ordered)
- 2Optional, Axial O-ring Face Seal Connections (Must Specify At Time Of Order)
- 3Threaded, Interface Mounting Holes
*Some applications using Chemical or water-based media may require alternative sealing materials. Applications above 220° F (105° C) require alternative seal materials. Please consult with DSTI for approval. 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.
