BFS1016-BFS1010

Circulation in accordance with API 682 / ISO 21049: Plan 52, Plan 53A
BFS1016 system is employed for applications in sealing systems with a wide variety of operating parameters for supplying buffer/barrier fluid to double and tandem mechanical seals. The BFS1016 system is available in standard sizes with flat ends, sight-glasses for level monitoring and with or without cooling coil. BFS1016 system is equipped as a standard with all the necessary system connections and brackets

Available with or without cooling coil
All connections of the systems are side faced
Compact design of the system allows low space requirements
Modular design combination available with a wide variety of system components and instruments selection possible such as, level switch, circulation pump, hand refill pump, thermometer, base frame etc.
Design allows for varied applications due to construction in stainless steel with borosilicate sight-glasses

The BFS 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.
