Metal Bellows Seals - BX
About this product
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.
Features and Benefits
- Longer service life via 0.20 mm (0.008 inch) thick standard welded bellows for maximum resistance to corrosion, shaft vibrations and centrifugal forces.
- 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
