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!
