8000 Series Endura Split Flange Swivels
The Endura™ Dual Split Flange (DSF) swivel joint from OPW® Engineered Systems represents the best in swivel technology. Specifically designed for the transfer of hazardous materials such as acids, solvents, petrochemicals and other toxic fluids, Endura™ sets the standard in Loading Arm Swivel performance.
- Standard Sizes: 2 in., 3 in., 4in.
- Standard Materials: Carbon Steel, Stainless Steel
- Standard Seals: Buna-N, Fluorocarbon, PTFE, EPDM, Neoprene
- End Connections: FNPT, 150/300 ANSI Flanges, Butt Weld
Features & Benefits
- Endurance – Heavy-duty construction and unique design features result in long-life, hassle-free operation
- Improves Uptime Performance – Endura™ DSF swivel technology, combined with the most user-friendly counterbalance solutions,results in LESS DOWNTIME–LESS LABOR– LESS COST!
- Lowest Overall Cost of Ownership – Optimized performance, downtime prevention and reduced maintenance time and costs make this the best overall loading arm solution currently available.
- Redundant Sealing for added safety!
- Incorporates a main seal, back-up seal, and environmental seals
- If main product seal ever leaks due to normal wear, the back-up seal contains the fluid
- Any main seal leakage would be channeled to leak detection port
- Environmental seal provides a third layer of protection
- Bearing Module for easy maintenance
- Deep groove replaceable dual & single race ball bearing technology
- Easy replacement or rebuild options
- Ball removal not required to access main seals
- Endura™ 8800-8900 series feature ALL stainless steel construction
- Easy Maintenance
- Simply unbolt sealing flanges to access seals
- No ball bearings to remove
- Leak Detection Port
- In the event of main seal leakage, fluid would be channeled to leak detection port
- Quick & easy way to monitor performance so that maintenance can be performed
- Purge Port
- For critical applications, an inert gas can be injected at leak detection/purge port
- Inert gas pressure higher than product pressure to virtually eliminate risk of fugitive emission.
- Recommended for your extreme applications!
