BX Series balanced metal bellows seals are engineered to drive exceptional, long-term equipment reliability and lower energy consumption. They provide exceptional reliability in corrosive and non-corrosive fluids, especially fluids that crystallize or coke in atmospheric conditions. The BX Series is fully compliant with API 682 Type B requirements. Available in single and dual seal configurations.

- Optimal performance is attained by selecting from three standard seal face balances; the BXQ seal is high balanced for flashing hydrocarbon applications
- Increased maintenance intervals due to a self-cleaning rotating bellows that replaces the need for springs and dynamic elastomers to lessen clogging vulnerabilities
- Maintain the performance benefits of self-cleaning rotating bellows in dual pressurized Arrangement 3 seals with the BXB seal’s unique ID pressurized seal face balance
