ELS™ Rotary Joints (US Patent No. 5,226,677)
The ELS (Extended Life Series) rotary joint is a self-supported joint that has been specifically designed to solve accelerated wear problems that occur with conventional self-supported rotary joints – particularly those in high vibration applications. The double-guide design provides internal support for the joint and maintains alignment even when the roll or cylinder is not concentric. The ELS is available in single-flow or with stationary syphon dual-flow configurations for steam service. Sizes range from 1.25” up to 10” and the joint is rated up to 650° F (343° C), 310 psig (20 bar) and 200 RPM.
Features
- Designed for steam service
- Two internal support guides
- Renewable wear plate
- Maximum carbon guide separation
Benefits
- Application specific performance
- Increased life and reliability
- Lower maintenance and repair cost
- Improved joint and syphon support
