Wear Rings


Open and Ground Tolerances

Hyperion Materials & Technologies manufactures cemented carbide (solid carbide or tungsten carbide (WC)) mechanical seals that provide outstanding material performance in corrosive and abrasive environments. Hyperion seal faces help to minimize leakages by maintaining a stable sealing gap due to high mechanical strength and stiffness. Cemented carbide seal rings can be engineered to fit your specific needs.


• Wear Rings

• Seal Rings

• Ground tolerances up to µm level

• Shape features as chamfers, radii, slots, and holes

• Inner and outside profiles

• Laser engraving

• Surface finishes: standard, matte, and mirror

• Flatness: down to 1 to 2 light bands


• Reduced maintenance costs as seal faces maintain flatness under high loads thus minimizing leakage due to the high mechanical strengths and stiffnesses of Hyperion’s specialty carbides

• Excellent material performance in water/food applications with Hyperion’s unique selection of alloyed binder grades

Easy to assemble and resistant to handling

• Reliable and consistent material thanks to the more than 60 years’ experience of developing cemented carbide grades
