TheT2 is a versatile machined mechanical seal engineered to perform reliably across a wide range of industrial pump systems and operating conditions. It serves as a high-quality replacement for industry-standard models such as John CRANE 2 (US), AESSEAL P04U, and FLOWSERVE 52. Whether your application requires enhanced chemical resistance, improved wear performance, or custom adaptations for unique environments, our engineering team can provide tailored configurations to ensure optimal sealing efficiency and long-term equipment protection.
- Versatile Material Combinations: Available in Carbon/Ceramic, Resin Carbon/Ceramic, SiC/SiC, and TC/TC to suit various media.
- Robust Operating Limits: Designed to handle pressures up to 2.8MPa and rotational speeds up to 13m/s.
- Broad Temperature Tolerance: Reliable performance in environments ranging from -30°C to +200°C.
- High-Grade Components: Features rotary rings (Carbon/SiC/TC), stationary rings (Ceramic/SiC/TC), and secondary seals (NBR/EPDM/VITON).
- Durable Construction: Springs and other metallic parts are manufactured from high-quality SUS304 or SUS316 stainless steel.
- Customizable Design: Capability to modify materials or design entirely new seal types to meet specific client needs.
