Parts in the Pumping Industry:

  • Plungers
  • Pistons
  • Valves
  • Gears
  • Screws
  • Impellers
  • Rotors
  • Shafts
  • Bushings and Sleeves
  • Case Rings

Requirements for the parts:

  • For high Hardness
  • For high Wear resistance
  • For high Fatigue strength
  • For Plastic deformation resistance
  • For Lower friction

Ion Nitriding Solutions:

  • Significantly increasing the surface hardness, wear resistance and fatigue life of the parts, improving their lifespan and performance.

  • Reducing the friction coefficient.
  • Increasing the corrosion resistance.
  • Post-Oxidation can be done after nitriding in the same process for further increase in corrosion resistance.


Improving these parameters will save from downtime and maintenance costs.

Steel Grades Used:
