BFS 54 Barrier Pressure Unit – Seal Supply Systems
Description
Typical Industrial Applications
- Chemical industry
- Oil and gas industry
- Petrochemical industry
- Refining technology
BFS range of barrier pressure units are designed to perform various functions of a barrier system which is essential for operating double seals (circulation and cooling of the barrier medium, pressurization of the barrier fluid, and compensation of leakage).
The BFS systems are designed to operate with hydraulic oil having viscosity values ranging from 12 to 90 mm2/s under normal operating temperature of the equipment.
The final selection of optimum viscosity of the oil to be used has to be ascertained independently in accordance with the respective operating parameters of the equipment.
Technical Features
1. For reducing barrier fluid pressure at standstill an automatic relief valve is provided
2. Reversible double filter is provided for the fluid to pass through the oil cooler
3. Level Switch with contact for minimum level
4. Barrier fluid pressure can be controlled manually
5. Maximum operating temperature in the tank oto be maintained at 80C (return line omaximum 90 C)
6. For monitoring the pump discharge pressure (outside the circuit) an additional pressure connection is provided
7. Temperature monitoring is achieved by providing a return line and tank thermometer
