Large Diameter Seal Faces

Large Diameter Seal Faces

JJISCO specializes in large seal face components in custom and semi-standard designs to meet your specific application requirements. These seals will operate at temperatures up to 1500°C in corrosive, abrasive environments. We thrive on unique geometries, and yet still welcome typical designs. JJISCO has large diameter capabilities up to 27” [700mm] in silicon carbide and 18” [450mm] in tungsten carbide.

In mechanical face and sealing applications, wear can occur due to diverse environmental conditions, abrasive media, slurries, and shaft deflections. This may ultimately cause a complete failure of the seal. To combat this, JJISCO offers the following material options to ensure our seals will not fail:

 

  • Silicon Carbide – JJISCO’s AlphaLAST® sintered silicon carbide is an extremely hard and wear-resistant material for the best chemical resistant applications.
  • Tungsten Carbide – Our NiLAST® (WC-Ni) and BlackLAST® (WC-Co) tungsten carbide can withstand extreme wear, corrosion, impact, loading, and deformation.
  • Aluminum Oxide (Alumina) – AlumaLAST® aluminum oxide offers superior chemical resistance where purity of materials is required. Under challenging environments, AlumaLAST offers an excellent combination of lower cost and long life.
  • Zirconium Oxide (Zirconia) – JJISCO’s ZiaLAST® zirconium oxide offers excellent wear resistance where high strength in conjunction with purity of material and chemical resistance is required.

We provide axial designs, including seal faces in mechanical seals. We offer all types, standard and custom, as well as steam joint and valve seats. We also offer radial designs, including multi-segmented rings, shaft seals, gas seals, control rings, and seals for regulating devices.
