Why Choose FLUITEN BM6B?
The BM6B is a zero-emission, double-balanced pusher seal designed for medium-pressure, hazardous, or polluting fluid applications. It features a pressurized barrier fluid system, robust ring drive, and compact cartridge design to ensure reliable, emissions-free performance under heavy mechanical stress.
Key Technical Specifications
Seal Type: Double-balanced, face-to-back pusher design with pressurized barrier fluid
Barrier Fluid System: Maintains compression on seal faces to prevent emissions while resisting reverse pressure
Seal Rings:
Stationary: Reaction-bonded SiC (U41) , sintered SiC (U31) , or solid tungsten carbide (K21)
Rotating: Antimony-impregnated graphite (Z11); optional embedded SiC (U42/U32) or tungsten carbide (K22)
Gaskets: Seals molded from FKM , EPDM , or FFKM for stationary ring , rotating ring , sleeve , and flange
