SE Series Rotary Unions & Joints
The SE Series multiple passage rotary unions are available in 2, 4, 6, 8, 12, 16 and 24 passage models. These rotary unions are designed for applications with high pressure and limited space requirements. Features include specialized seals suitable for vacuum and bidirectional pressures up to 7,500 PSI [515 BAR] and independent flow passages capable of transferring different types of media simultaneously.
All SE Series models come standard with threaded connections on the sides of the shaft and housing. Models are also available with optional shaft O-ring glands for face/flush mounting (which must be specified when ordering).
Need to combine fluid with electrical power, signal and/or data transfer? No problem. The SE Series rotary unions are designed to integrate directly with our standard electrical slip rings. See options
- 1Standard, Radial SAE-ORB or BSPP Connections (Plugged if Axial Connection Type is Ordered)
- 2Optional, Axial O-Ring Face Seal Connections (Must Specify At Time Of Order)
- 3Threaded Mounting Holes
*Suitable Water/Glycol or Coolant media must have rust inhibitors present. Oil/Hydraulic media must be petroleum-based. 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.
