• Face Geometry: The faces are engineered to maintain a stable fluid film even in slurry conditions, preventing dry running during snoring (air intake) operation.
• Corrosion Resistant Binder: We use corrosion-resistant binder materials in our TC to prevent leaching in acidic mine water.
Key Features
• Slurry Specialist: Designed specifically for Flygt submersible pumps operating in mining, construction dewatering, and heavy sludge applications.
• Solid TC Construction: Uses premium Tungsten Carbide faces that resist the scouring action of sand, rock dust, and cement slurry.
• Plug-in & Cartridge Variants: Available as a direct replacement for both the older "Plug-in" seals and the newer "Griploc" or cartridge styles found in Flygt 2000 and 3000 series.

Case Study
Tunnel Construction: Submersible pumps removing bentonite slurry were failing weekly. We supplied Flygt TC Bellow Seals. The extreme toughness of the TC faces handled the abrasive bentonite, allowing the pumps to run until the project phase completion.
Testimonials
These are the armor our Flygt pumps need. We put them in the toughest sumps and they just keep running.
