Pressure Booster

Pressure Booster

Mechanical seal Pressure Booster

The BJSEAL Pressure Booster System (PBS) is specifically designed for API 682 / ISO 21049 Plan 53C pressurized dual mechanical seals. It utilizes a piston-based principle to maintain a stable differential pressure between the spacer fluid pressure and the pump medium pressure, ensuring optimal seal performance in fluctuating conditions.

Working Principle

  • The pressure booster operates on the piston principle, where the spacer fluid (barrier fluid) is pressurized automatically by the process medium pressure.
  • As the process medium pressure fluctuates, the PBS system automatically adjusts the barrier fluid pressure to maintain a consistent differential pressure, preventing seal failures.
  • The pressure source for the spacer fluid is directly derived from the medium pressure, eliminating the need for external pumps or regulators.
  • The system requires that the process fluid is clean and does not affect the piston movement to ensure long-term reliability.
