The LIE/TS-712 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 LIE/TS-713 system it is possible to supply buffer/barrier fluid to double and tandem mechanical seals for a broad range of applications. The LIE/TS-713 thermosyphon vessel is available in 2 standard sizes with flat ends, sight-glasses for level monitoring and with or without cooling coil. LIE/TS vessels are equipped as standard with all the necessary system connections and brackets. The modular system allows the LIE/TS-713 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, Pressure Gauge 0-10, 0-25, 0-40 bar Level Gauge To indicate barrier fluid etc.
