The WB2 static ring series (A-type (flat ring) pressureless silicon carbide sealing ring) serves as the static ring component of the A-type (flat ring) pressureless silicon carbide sealing ring. It adopts A classic planar structure and is A general-purpose sealing part. It is easy to install and has strong versatility. Its core function is to provide stable and reliable end face seals under high-speed and chemically unstable working conditions, preventing fluid leakage in pumps, reactors and other equipment. It has good wear resistance and dimensional stability, can adapt to a certain range of temperature and pressure fluctuations, and is suitable for pump body seals, compressors and other general rotating equipment with water, oil and mild chemical media. It is one of the commonly used standardized configurations of mechanical seals. Meanwhile, the pressureless silicon carbide material offers a long wear-resistant service life, which can reduce the cost of equipment maintenance and re…
