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. Operating Parameters Pressure: up to 27.6 bar (400 psi) Temperature: -40°C to 204°C (-40°F to 400°F) Speed: up to 23 m/s (75 fps) Sizes: 12.3 to 127 mm (0.483 to 5.000 inches) FEATURES & 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
