Wear Rings/Thrust Washers

 JJISCO offers wear ring and thrust washer components in custom and standard designs to meet your size, shape, and material requirements. Our products are designed to aid manufacturers enhancing performance and reducing down time. JJISCO-engineered silicon carbide and ceramic materials will operate at temperatures up to 1900° F in corrosive or abrasive environments.

  • Backup rings
  • Shaft rings
  • Thrust washers
  • Thrust pads

We have demonstrated proven success in a wide variety of applications and pump design types, including: 

  • Centrifugal pumps
  • Magnetically-driven pumps/Mag drive
  • Vane pumps
  • Vertical pumps
  • Down hole pumps
  • Valve plates, washers, and seats

In severe applications, wear can occur due to abrasive media, chemical corrosion, and excessive force, and may ultimately cause a complete failure. JJISCO utilizes extremely hard and wear-resistant materials for radial and thrust loads. Key material characteristics include: superior hardness and high strength, high abrasion and wear resistance, and extreme corrosion resistance.

Based on your requirements, we offer multiple hard material options for the best cost-benefit solution.

Silicon Carbide AlphaLAST® and Extrema® 

Aluminum Oxide (Alumina)AlumaLAST®

Tungsten Carbide – NiLAST® (WC-Ni) and BlackLAST® (WC-Co)
