BFS 1000

The BFS performs all the basic functions of a buffer/barrier system for the operation of double seals:
  • To pressurize the buffer chamber
  • Leakage compensation
  • Buffer/barrier fluid is circulated by thermosyphon effect or forced circulation system
  • To cool the seal
  • To selectively absorb product leakage and prevent dry running (tandem arrangement)
  • Use compressed air or nitrogen for pressurization

With BFS 1016 system it is possible to supply buffer/barrier fluid to double and tandem mechanical seals for a broad range of applications. The BFS 1016 thermosyphon vessel is available in 2 standard sizes with flat ends, sight-glasses for level monitoring and with or without cooling coil. BFS vessels are equipped as standard with all the necessary system connections and brackets. The modular system allows the BFS 1016 vessels to be combined with a wide range of system components such as, e.g. level switch, circulation pump, hand refill pump, thermometer, base frame, etc. Circulation in accordance with API 682 / ISO 21 049: Plan 52, Plan 53A
