WCURC Cartridge mechanical seal replace AES CURC mechanical seals

The AESSEAL CURC, CRCO and CURE mechanical seals are part of a range of seals specifically designed to optimize the use of Silicon Carbide.
All these seals incorporate improved third generation self-aligning technology. The design objective was to minimize metal to Silicon Carbide impact, particularly on start–up.

In some seal designs, impact between metal anti–rotation pins and Silicon Carbide can be sufficiently severe to induce stress cracking in the Silicon Carbide.

Silicon Carbide has many advantages when used in mechanical seals. The material has superior chemical resistance, hardness and heat dissipation properties compared to practically any other material used as a mechanical seal face. Silicon Carbide is, however, brittle by nature, so the design of the self–aligning stationary in the CURC range of mechanical seals seeks to minimize this metal to Silicon impact on start–up.
