Mak-Tech Seals

Jogeshwari West, Mumbai, Maharashtra

The MAK-TECH SEALS Thermosiphon systems of the SBF6000 range meet all the requirements to supply mechanical seals in accordance with the API 682 guidelines. The vessels are equipped with all essential connections for fitting additional components. The range is available in two standard vessel sizes (shown: SBF6000) with dished heads; a version which can be dismantled is also available as an option. The modular system allows the SBF6000 vessels to be combined with a wide range of system components such as, level switch/transmitter, pressureswitch/transmitter, base frame, etc. Circulation in accordance with API 682 / ISO 21049: Plan 52, Plan 53A

Functional DescriptionThe SBFS system 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 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 switch.
• The incorporated level switch issues a signal whenever the level of buffer/barrier fluid is too low.

Typical Industrial Applications

• Refining technology
• Oil and gas industry
• Chemical industry
• Petrochemical industry

Technical Features
