DuraHard® Coatings

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

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

DuraHard® 7: Enhanced abrasion and corrosion-resistant coating 

• High phosphorus nickel coating for added hardness of stage materials
• Effective in high temperature, abrasive, and corrosive conditions
• Protects ESP system 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
• Protects pumps from angular abrasive sands and quartz sand
• Effective in extreme temperatures, highly abrasive, and corrosive environments
