Why Choose FLUITEN TR6S?
The TR6S combines a balanced , single-design with a rotating metal bellows , making it perfect for sealing non-toxic, non-polluting fluids that crystallize or solidify in air. Its bellows drive replaces springs and O-rings (avoiding clogging), and it tolerates both axial and radial shaft movements , ensuring robust performance under variable conditions.
Key Technical Specifications
Seal Type: Balanced single with rotating metal bellows (API 682 Cat II, Type B)
Stationary Ring Materials: Reaction‑bonded silicon carbide (U41) , sintered silicon carbide (U31) , or solid tungsten carbide (K21)
Rotary Bellows & Inserted Ring Options:
Bellows: AISI 316L with Hastelloy alloy
Rotary rings: Graphite-antimony (Z12) , silicon carbide (U32) , or tungsten carbide (K22)
Secondary Seals: Static O-ring gaskets in FKM , EPDM , or FFKM for rotary ring, stationary ring, sleeve, and flange
Containment Bushing: Floating carbon bush to collect minor leakage
Drive Mechanism: Bellows-driven operation avoids clogging and adapts to shaft movement
Flange & Sleeve Configuration: Slotted flange with custom shaft sleeve; includes multipoint injection ports for flush , wash , or drainage
Typical Applications
Pumps handling liquids that crystallize or solidify on exposure to air, without external washing capability
API-compliant horizontal and vertical pump systems
Situations where clog-resistant sealing and movement tolerance are critical
Additional Features
Rotating metal bellows eliminate clogging and ensure reliable sealing
Static sealing design reduces dynamic failure points
Floating carbon bush collects leakage while allowing bellows flexibility
Multipoint injection capability supports flushing or draining in challenging fluid systems
Compact cartridge format simplifies installation and retrofit
The FLUITEN TR6S is a high-reliability metal bellows seal designed for challenging services. It offers clog-resistant performance, dry capability, and shaft movement tolerance, delivering durable, low-maintenance sealing for critical pump applications in demanding fluid environments.
