DuraHard® Coatings


Abrasion and corrosion-resistant coatings for less material loss, longer run time

DuraHard® coatings protect against a wide range of abrasive and corrosive conditions. Choose the coating best suited to your needs, from basic friction and corrosion resistance to material strength approaching carbide. All coatings are temperature resistant to 500°F (260°C).

DuraHard® 3: Basic reduced friction and corrosion-resistant coating

  • Patented multilayer process for complete coverage and enhanced bonding
  • Non-stick coating for preventing scale and asphaltene build-up
  • Reduced friction on running surfaces for optimal performance

DuraHard® 7: Enhanced abrasion and corrosion-resistant coating

  • High phosphorous nickel coating for added hardness of stage materials
  • Proprietary heat-treat, ensuring surface hardness
  • Effective in high temperature, abrasive, and corrosive conditions
  • Protects electric submersible pump (ESP) systems in recently fractured and cased hole wells with sand issues

DuraHard® 15: Extreme abrasion and corrosion-resistant coating

  • Coating material creates molecular bond with base metal for hardness approaching carbide
  • Ductility to coat and bond steel components
  • Protects pumps from very angular abrasive sands and quartz sand
  • Effective in extreme temperature, highly abrasive, and corrosive environments
