NP Industrial Gear Oils

Overview

NP Industrial Gear Oilis a premium quality, lead-free, extreme pressure (EP) gear oil utilizing sulphur-phosphorus EP technology. This results in an overall performance level superior to leaded EP gear oils, while at the same time satisfying environmental requirements. NP Industrial Gear Oil is manufactured from premium quality hydro-treated base oils, which contain lower levels of impurities, and are blended with an advanced additive package, incorporated to enhance the:

  • Anti-wear performance
  • Corrosion protection
  • Oxidation stability
  • Thermal stability
  • Anti-foam properties

Benefits

The use of NP Industrial Gear Oilswould result in:

&US Steel Requirement 224
&AGMA 9005 – D94
&David Brown S1.53.101E
&DIN 51517 Part 3
&API GL-5, GL – 4
  • Minimizing wear of heavy and shock loaded enclosed gears.
  • High load carrying capacity in steel gear transmissions.
  • Good anti-friction characteristics in steel/phosphor-bronze gear units.
  • Less downtime and longer gear-set working life.
  • Good oxidative and thermal stability in systems with bulk oil temperatures up to 100oC.
  • Minimizing of harmful sludge and emulsions.

Details

Main Applications

  • Recommended where the use of EP lubricants are specified or required.
  • Enclosed industrial gear drives, including worm gears.
  • Steel/Phosphor-bronze gear sets.
  • High load carrying capacity in steel gear transmissions except for automotive hypoid gears.
  • Circulating and splash lubricated systems and may also be used in oil mist applications.
