MS-BFS 2000
FUNCTIONAL DESCRIPTION
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 external
circulation system.
* To coll the seal
* To selectively absorb product leakage and prevent dry running
(tandem arrangement)
* Use compressed air or nitrogen for pressurisation.
PRODUCT DESCRIPTION
* Circulation in accordance with API 682 / ISO 21049: Plan 52, Plan 53A
* BFS 2000 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 BFS 2000 system is available in standard sizes with flat ends,
sight-glasses for level monitoring and with or without cooling coil. BFS
2000 system is equipped as a standard with all the necessary system
connections and brackets.
* 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.
TECHNICAL FEATURES
* Available with or without cooling coil
* Optimum drainage and venting is achieved because of the design of
cooling water connections at top (OUT) and bottom (IN)
* Sockets are designed with recessed gasket to avoid contamination of
the circuit by thread sealant
* Construction of the BFS 2000 is designed for demanding operating
conditions up to 30 bar/200℃
* Design allows for varied applications due to construction in stainless
steel with borosilicate sight-glasses
