Chemical Sector Applications Overview
Applicable to the transportation of various highly corrosive media and continuous reaction equipment. The pump seal needs to maintain long-term stable operation to avoid leakage that could cause process interruption.
In environments involving strong acids, strong alkalis, and oxidising agents, sealing materials must possess high corrosion resistance to ensure system safety and equipment longevity.
For sanitary-grade reactors and stirring systems. Seals must comply with requirements such as FDA and USP Class VI to ensure product purity.
Commonly employed in high-temperature, high-pressure, continuous-duty circulation pumps. Mechanical seals must withstand volatile media and meet stringent leakage control standards.
Suitable for organic solvents, additives and catalytic systems. Seals must possess strong solvent resistance and wear resistance, suitable for high-viscosity or complex materials.
Specifically designed for the conveyance of corrosive sewage and waste liquids containing solids. The seal requires enhanced wear resistance and anti-scaling capabilities to reduce maintenance frequency.
