Barrier/buffer fluid system

Features

The EagleBurgmann barrier/buffer fluid systems of the TSA6 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.
Available as bottom flanged version (TSB6) which can be dismantled for optimized and easy cleaning purpose of the inside of the vessel.
The modular system allows the TSA6/TSB6 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 50 bar / 200 °C
    (725 PSI / 392 °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 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

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
- As 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 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.
