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.

A single cartridge stationary seal with integral Plan 23. Coupled with a Heli coil cooler. The seal provides the most efficient sealing solution for this piping arrangement. Extremely effective Plan 23 with bi-directional integral pumping ring, ideal for boiler feed and boiler circulation duties.

Integral inboard restriction bush configuration, adapted to suit the equipment, total solution available including heat exchanger. Hydraulically balanced seal face technology for reduced power consumption, non-shaft-fretting sleeve elastomer and positive set screw drive. Multiple spring seal-face loading and stationary design suitable for high speed applications.
