  • Available with or without cooling coil
  • All connections of the systems are
    side faced
  • Compact design of the system allows
    low space requirements
  • Modular design combination available
    with a wide variety of system
    components and instruments selection
    possible such as, level switch,
    circulation pump, hand refill pump,
    thermometer, base frame etc.
  • Design allows for varied applications
    due to construction in stainless steel
    with borosilicate sight-glasses
  • The BFS system performs all the basic functions of
    a buffer/barrier system for the operation of double
  • To pressurize the buffer chamber
  • Leakage compensation
  • Buffer/barrier fluid is circulated by thermosiphon
    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.

  • Water and waste water technology
  • PED 2014/68/EU (Design and production in
    accordance with EU Pressure Equipment Directive)
  • Circulation in accordance with API 682 / ISO

  • BFS1016 system is employed for applications
    in sealing systems with a wide variety of
    operating parameters for supplying
    buffer/barrier fluid to double and tandem
    mechanical seals. The BFS1016 system is
    available in standard sizes with flat ends,
    sight-glasses for level monitoring and with or
    without cooling coil. BFS1016 system is
    equipped as a standard with all the necessary
    system connections and brackets.
