• High-Strength Bellows: We use premium elastomer bellows that provide strong torque transmission to the TC face, preventing slippage.
• Solid Face Design: Unlike some competitors who use inserted faces, our TC faces are solid or securely shrink-fitted, ensuring maximum heat transfer and stability.
Key Features
• Roten Heavy Duty: A rugged upgrade for Roten Type 2, Type 3, and Type 5 style seals, replacing standard carbon/ceramic faces with solid Tungsten Carbide.
• Compact Durability: Maintains the short working length of Roten seals while offering industrial-grade wear resistance.
• Universal Compatibility: Fits a wide range of European pumps (e.g., Calpeda, Ebara, Pedrollo) that utilize Roten-standard seals.

Industry Solutions
Case Study
Car Wash System: High-pressure pumps in a car wash were wearing out seals rapidly due to grit and wax. We installed this Roten-style TC seal. The Tungsten Carbide withstood the abrasive road grime, tripling the maintenance interval.
Testimonials
Fits perfectly in our Calpeda pumps. The tungsten faces make a huge difference in dirty water applications.
