- Available with or without cooling coil
- Optimum draining 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°C - 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 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
- The BFS vessel must always be installed higher
than the mechanical seal. The buffer/barrier fluid
flows via the return pipe into the vessel and is
cooled. The exchange of fluid takes place by the
thermosiphon principle or by forced circulation,
e.g. with a pumping screw. Connection pipes to
the seal should be designed with as little
resistance as possible. - Measuring unit
- Level Switch
- From PCV, we recommend using a reverse
controlled pressure control valve (PCV) - Hand Refill Pump
- Circulating Pump
- Mechanical seal
- Chemical industry
- Oil and gas industry
- Petrochemical industry
- Refining technology
- PED 2014/68/EU (Design and production in
accordance with EU Pressure Equipment Directive) - ASME VIII, Div.1 (Design, calculation and production)
- 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. - Circulation in accordance with API 682 / ISO
