Key precision components for mechanical sealing systems
Our Carbide Seal Rings are engineered for mechanical seals, dry gas seals, pumps, valves, and rotating equipment operating under abrasive, high-pressure, or high-speed conditions.
Carbide Seal Rings are key precision components in mechanical seals, dry gas seals, and high-wear-resistant seal pairs, typically used as rotating rings, stationary rings, or matched seal faces.
Manufacturing & Quality Control
Our carbide seal rings are produced through controlled powder preparation, pressing, sintering, densification, precision grinding, lapping, and polishing.
- Control of seal face flatness and parallelism
- Consistency of inner diameter, outer diameter, and assembly positioning
- Surface roughness and grinding mark direction control
- Control of micro-cracks, edge chipping, and grinding burns
- Matching control with mating rings and metal seats
Selection Recommendations
Choose the right seal ring for your application:
- **High-speed seal applications**: focus on end face flatness, surface roughness, and fit precision
- **Particle-containing or slurry media**: prioritize higher wear resistance grades
- **Corrosive media or water lubrication**: consider binder phase system and thermal shock risks
