The C3 Cartridge Seal is a premium double cartridge mechanical seal engineered for critical industrial
applications requiring maximum leakage control, enhanced safety, and superior operational reliability. Designed
as a fully integrated cartridge unit, the C3 seal eliminates installation complexities and ensures precise seal
alignment, reducing maintenance time and preventing common installation errors. Its double seal configuration
provides an additional layer of protection through the use of a barrier or buffer fluid system, making it
particularly suitable for hazardous, toxic, abrasive, volatile, or environmentally sensitive process media. The
robust multi-spring design delivers uniform face loading and stable sealing performance under demanding
operating conditions, while minimizing wear and extending seal life. Ideal for pumps, reactors, mixers, agitators,
and process equipment operating in chemical processing, petrochemical plants, refineries, pulp and paper
industries, and other heavy-duty industrial environments, the C3 seal offers exceptional reliability in continuous
service applications. Manufactured using premium-grade face materials such as Carbon, Silicon Carbide, and
Tungsten Carbide, the seal provides excellent resistance to abrasion, corrosion, and thermal shock. Secondary
sealing options including FKM, NBR, EPDM, and PTFE ensure broad chemical compatibility, while metal
components in SS304, SS316, SS316L, Alloy 20, and Hastelloy-C offer outstanding corrosion resistance. Available
in shaft sizes from 20 mm to 300 mm, operating temperatures up to 220°C, and pressure capabilities up to 35
kg/cm², the C3 Cartridge Seal delivers long-term performance, improved equipment reliability, reduced
emissions, and lower lifecycle costs. Its advanced double-seal technology makes it the preferred solution for
industries where process safety, environmental compliance, and uninterrupted operation are critical
requirements.
