• High-Torque Drive: We use premium elastomer bellows that provide strong torque transmission to the TC face, ensuring it doesn't slip under load.
• Solid Face Construction: Unlike some competitors who use thin inserted faces, our TC faces are solid or securely shrink-fitted for maximum durability.
Key Features
• Heavy-Duty Roten: A rugged upgrade for Roten Type 2, Type 3, and Type 5 style seals, replacing standard faces with solid Tungsten Carbide (TC).
• Shock & Impact Resistant: TC is tougher than Silicon Carbide, making it the ideal choice for pumps that experience cavitation, water hammer, or vibration.
• Dirty Water Ready: Resists abrasion from sand, rust, and scale, significantly extending seal life in non-potable water applications.

Industry Solutions
Case Study
Car Wash: High-pressure pumps in a car wash were wearing out seals 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.
