The GFK Mechanical Seal is a high-performance metal bellows sealing solution designed for demanding pump applications. Unlike conventional spring seals, this model uses a metal bellows structure that eliminates dynamic O-rings, reducing friction and improving sealing reliability under extreme conditions.
With a standard size of 22mm, this seal is ideal for medium-duty industrial pumps requiring stable and consistent performance. The combination of carbon (graphite), silicon carbide, and tungsten carbide sealing faces ensures excellent resistance to wear, high temperatures, and aggressive media.
Equipped with metal bellows and high-quality materials such as VITON and stainless steel (SUS304/SUS316), the GFK provides superior corrosion resistance, durability, and long service life, making it suitable for critical and continuous-duty operations.
