HuaCera^® silicon carbide mechanical seal rings are lightweight, have a low coefficient of thermal expansion, high hardness, and excellent high-temperature strength. They also offer excellent dimensional stability even at extremely low and high temperatures. They also possess strong corrosion resistance, a high elastic modulus, wear resistance, and a long service life. They can be used in complex operating conditions such as those involving radioactive, corrosive, highly toxic, flammable, explosive, and high-temperature environments.

Typical applications of HuaCera^® SiC mechanical seal rings

• Pump seals (pumps for refining and petrochemical processes, power plant process pumps, general industrial pumps, chemical pumps, marine pumps, centrifugal pumps, submersible pumps, nuclear reactor cooling water pumps);
• Agitators and mixers used in the chemical, pharmaceutical, and food processing industries;
• Rotary joints;
• Compressors in the petrochemical and natural gas industries;
• Seals for water turbines and ship propulsion shafts;
• Especially suitable for harsh applications, such as those handling contaminated fluids, abrasive fluids, and/or strongly corrosive fluids.

Huashuo Advanced Ceramics provides SSiC flat rings, single-stage and double-stage SiC rings, and customized complex-shaped silicon carbide rings.

SiC Dry Gas Seal Rings

The combined properties of HuaCera^® silicon carbide's high mechanical strength, excellent thermal conductivity, high stiffness and corrosion resistance enable HuaCera^® dry gas sealing rings to achieve a high level of performance.

The ultra-high strength of HuaCera^® XA material is especially suitable for high-speed compressor applications. Huashuo Advanced Ceramics offers dry gas seal rings for compressors with various shaft diameters. They can be used under operating pressures up to 20MPa, temperature ranges from approximately -200°C to +500°C, and linear speeds up to about 160 m/s.

HuaCera^® silicon carbide dry gas seal rings minimize dry gas seal leakage and maintenance. Use HuaCera^® silicon carbide dry gas seal rings for gas compressor seals.
