What is a Rotary Union? A rotary union (or swivel joint) is a mechanism used to transfer fl uid (under pressure or vacuum) from a stationary inlet to a rotating outlet, preserving and isolating the fl uid connection. Rotary unions are engineered to endure a wide range of temperatures and pressures for a variety of conditions and environments. n addition, rotary unions may integrate multiple passages and handle different types of fl uid simultaneously. See examples at www.dsti.com/industries ow do choose the best rotary union for my application? ell us about your requirements so we can make a recommendation: 1) ype of media(s) / fl uid(s) to be transferred 2) umber of independent fl ow channels (passages) 3) perating pressure 4) perating temperature 5) perating speed 6) Shaft & housing connection type 7) Flow channel (passage) size 8) orque & load requirements 9) Duty cycle* *Does the temperature, speed or pressure fl uctuate or change during operation? f so, please provide the detailed ranges for each parameter and time durations of each condition.

Rotary Union Solutions S nstallation & ounting ESE SRUCS ARE EDED BE USED AS A EERA UDE, EASE CSU E FACRY DSCUSS AY SECFC UESS REAED YUR SAA. REARA: Remove the rotary union from the shipping container. nspect the entire assembly, including all passage connections to make sure that they are clean and no visual damage occurred during transport. f the assembly is a rotary union/electrical slip ring, the electrical slip ring may be packaged separately to protect during shipping. f this is the case, mount the electrical slip ring to the rotating union assembly using the supplied hardware. RECEDED RARY U SAA RACCE: DS does not recommend mounting the rotary union with both the shaft & housing components solidly bolted into place. ne of the two components should be mounted in a manner that allows for some movement in the event of misalignment or run-out during rotation. Using only the supply lines or hoses to fix the stationary component in place is also not recommended. An anti-rotation arm that attaches to the stationary part of the rotary union assembly and rests against part of the equipment framework is recommended (see figure 1.1). U A RARY U W/ A EECRCA S R: ake sure the electrical wiring is fixed in place and protected from contact with other components or equipment. Care should be taken to make sure the slip ring area remains clean and dry during use. SAF U: -R AFD YE: ake sure the rotary union shaft face & equipment mounting surface is clean and free from dents or chips to insure proper installation. Equipment pilot bore needs to be concentric to the center line of the rotary union shaft to assure proper function. nstall face mount -rings into groove or counter bore in rotating union shaft face. eneral assembly grease can be used as needed to hold -rings into place during assembly. Align rotary union shaft with equipment pilot bore and flow passages, then insert into place. Bolt assembly into place using tapped holes or mounting flange on rotary union face. SAF U, READED CECS: When mounting the shaft using threaded connections, make sure all fittings are properly tightened & pipe thread sealant is used as required. Equipment mounting surface needs to be concentric to the center line of the rotary union shaft to assure proper function. After all fittings are in place, bolt assembly into place using tapped holes or mounting flange on rotating union shaft. A SAR-U: After rotary union is installed, a dry run is recommended to assure proper mounting of the rotating union assembly. Begin rotation of the equipment, and verify that while rotating at the maximum operating speed there is no visible movement of the rotary union assembly due to misalignment.
