The single passage SCS Series rotary unions feature hygienic, tri-clamp ferrule connections, food grade seals and bearing lubricant, and a FDA-approved design for use with CIP (Clean-in-Place) systems.

To help minimize fluid stagnation points, smooth flow lines are engineered into the design to allow a clear passage for fluid. Specialized bearings fit inside a sealed chamber to keep lubricants in and contaminants out.

The all-stainless steel SCS Series utilize high performance DSTI sealing technology and are available with ASME-BPE connections. If needed, DSTI can make modifications to meet each application's specific requirements including changes to the SCS Series mounting configuration, connections, sealing system, and housing or shaft dimensions. See options.

*Some applications using Chemical media may require alternative sealing 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.
