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!
