Flowway Corporation Ahmedabad, Gujarat

Functional description This 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 external circulation system to cool the seal to selectively absorb product leakage and prevent dry running (tandem arrangement) Use compressed air or nitrogen for pressurization.   Features With the Flowway thermosiphon system it is possible to supply buffer/barrier fluid to double and tandem mechanical seals for a broad range of applications. The range is available in 2 different pressure levels with dished heads, sight-glass for level monitoring and with or without cooling coil. TS vessels are equipped as standard with all the necessary system connections and brackets. The modular system allows the vessels to be combined with a wide range of system components such as, level switch, circulation pump, hand refill pump, thermometer, base frame, etc. Recommended applications Chemical industry Petrochemical industry Oil and gas industry Refining technology   Advantages Modular system: combination with a wide range of system components possible Vessel made of stainless steel / borosilicate sight-glasses: suitable for universal applications Available with or without cooling coil Sockets with recessed gasket: no contamination of the circuit by thread sealant
