C03 series is a robust, precision-engineered cartridge mechanical seal built to excel in extreme industrial environments. It is specifically designed to manage high-pressure operations up to 3.1MPa while maintaining stability at peripheral speeds of 25m/s. Featuring advanced material options like Hastelloy-C and Duplex steel, this seal offers exceptional resistance to chemical corrosion and thermal stress up to 205°C. Its balanced construction ensures a long service life and maximum leakage protection for mission-critical pumping systems.
- Superior Pressure Resistance: Engineered to operate reliably under high pressures up to 3.1MPa.
- High-Speed Performance: Optimized for stable operation at speeds reaching 25m/s.
- Thermal Versatility: Maintains seal integrity across a temperature range reaching 205°C.
- Advanced Metallurgy: Available in C-276, Duplex, and 316 Stainless Steel for maximum durability.
- High-Performance Sealing Faces: Utilizes Carbon, Silicon Carbide (SiC), and Tungsten Carbide (TC) for friction reduction
