Why Choose FLUITEN TR6L?
The TR6L is a balanced, single- seal featuring a rotating metal bellows and a stationary secondary containment face. It is tailored for fluids that crystallize or solidify upon contact with air, or in cases where fluid characteristics are undefined. The metal bellows drive removes springs and dynamic O-rings, preventing clogging and allowing for both axial and radial shaft movement.
Key Technical Specifications
Seal Type: Rotating metal with stationary containment (API 682 4th Edition, Category 2 “Hybrid”)
Stationary Ring Options: Dry-running graphite , reaction-bonded silicon carbide , sintered silicon carbide , or solid tungsten carbide
Rotating Bellows & Rings: AISI 316L bellows with Hastelloy; inserted rings include graphite, silicon carbide, or tungsten carbide
Secondary Containment: Stationary containment face supports dry-running and high peripheral speeds
Gaskets: Static O-rings available in FKM, EPDM, FFKM; optional Grafoil for high-temperature applications
Containment Bushing: Floating graphite auxiliary bush manages physiological leakage
Drive Mechanism: Bellows-driven operation avoids clogging and maintains seal during shaft movement
Flange & Sleeve: Slotted flange and custom shaft sleeve; includes multipoint injection ports for flush, vent, or leak control
Typical Applications
Pumps handling fluids that crystallize or solidify in open air, especially where no external flushing is provided
API-compliant horizontal and vertical pumps in chemical, petrochemical, thermal, or undefined fluid services
Environments requiring clog-resistant sealing and tolerance to shaft misalignment or movement
Additional Features
Fluigrid micro-textured faces reduce friction and heat generation
Rotating bellows eliminate spring clogging and enhance longevity
Stationary containment design allows dry-running at high speeds
Floating graphite bush and multipoint injection provide improved leakage control and cooling
Compact cartridge modularity simplifies installation and retrofit in existing pumps
The FLUITEN TR6L is a reliable, clog-resistant metal bellows seal with secondary containment, ideally suited for crystallizing or high-temperature fluid environments. With its innovative bellows drive, Fluigrid face technology, and robust cartridge design, it offers durable, low-maintenance sealing for critical pump systems.
