• Brazed Face Technology: For metal bellow versions, the TC face is vacuum brazed to the holder, ensuring it cannot spin out under high torque.
• Corrosion Resistant Binder: We use a Nickel-binder TC grade to prevent "leaching" corrosion in acidic mine waters or low pH sludge.
Key Features
• The Slurry Standard: The ultimate heavy-duty seal for Flygt pumps in mining, construction dewatering, and raw sewage intake.
• Impact Toughness: Solid Tungsten Carbide (TC) faces resist fracturing from heavy shocks (e.g., rocks hitting the impeller) far better than SiC or Ceramic.
• OEM Spec Match: Directly replaces the OEM "Hard-Face" option for Flygt 2000, 3000, and 5000 series pumps.

Case Study
Tunneling Project: Submersible pumps removing bentonite slurry were failing weekly. We supplied Flygt TC Bellow Seals. The 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.
