The A04 is a high-performance cartridge mechanical seal engineered for demanding rotating equipment operating at high velocities. This model is distinguished by its exceptional thermal stability and ability to handle significant pressure variations. Designed for a broad temperature range from -30°C to 200°C, it ensures reliable sealing in both cryogenic and high-heat applications. Its robust construction and balanced design make it a superior choice for critical industrial processes where efficiency and safety are paramount.
- High-Speed Capability: Optimized for stable operation at peripheral speeds up to 23m/s.
- Wide Temperature Range: Resilient performance from -30°C up to 200°C.
- Premium Metallurgy: Components available in C-276, DUPLEX, and 316 stainless steel for maximum corrosion resistance.
- Versatile Sealing: High-grade secondary seals (Viton, Aflas, Kalrez) to suit various chemical environments.
- Pressure Stability: Engineered to maintain integrity under working pressures up to 2.3MPa.
