Features

• Redundant Sealing
  • 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
  • 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!
