Barrier/buffer fluid system

Features

The EagleBurgmann barrier/buffer fluid systems of the TSB6000A4 range meet all the requirements to supply mechanical seals in accordance with the API682 4th edition guidelines. The vessels are equipped with all essential connections for fitting additional components.
TSB6 bottom-flanged vessels are available in two standard sizes. A version with dished heads (TSA6000A4) is also available.
The modular system allows the TSB6000A4 vessels to be combined with a wide range of system components, such as level transmitter, pressure transmitter, base frame, etc.

Advantages

  • Operating limits up to 44 bar / 260 °C
    (638 PSI / 500 °F): suitable for a wide range of demanding operating conditions
  • Robust design with weld-pad type sightglass for optimum visual level monitoring
  • Modular system: combination possible with a wide range of system components

Standards and approvals

  • API 682 / ISO 21049
  • API 682 4th ed. Cat. 2/3 - 2CW-CW
  • API 682 4th ed. Cat. 2/3 - 3CW-FB
  • API 682 4th ed. Cat. 2/3 - 3CW-BB
  • API 682 4th ed. Cat. 2/3 - 3CW-FF
  • API 682 4th ed. Cat. 1 - 2CW-CW
  • API 682 4th ed. Cat. 1 - 3CW-FB

Functional description

The TS system performs all the basic functions of a barrier/buffer system for the operation of dual seals:
- To pressurize the barrier/buffer chamber
- Leakage compensation
- Barrier/buffer 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; pressurization is monitored by a pressure transmitter (default). The incorporated level transmitter issues a signal whenever the level of barrier/buffer fluid is too low.
