NP Hydraulic Oils

Overview

NP Hydraulic Oils are premium anti-wear lubricants developed for use in both high and low pressure hydraulic systems for industrial and mobile applications. They are designed to provide efficient power transmission and outstanding lubrication of vane, gear and piston type pumps, actuators, control valves and hydraulic system components.

NP Hydraulic Oils are manufactured from premium quality hydro-treated base oils, which contain lower levels of impurities, and are blended with an advanced additive package. Without these impurities, that limits the performance of conventional base oils, the use of NP Hydraulic Oils result in:

  • Proven field performance
  • Excellent rust and corrosion protection
  • Outstanding oxidation and thermal stability
  • Anti-wear performance
  • Longer lubricant life
  • Demulsibility
  • Superior hydrolytic stability
  • Low filter blockage tendency

Benefits

The use of NP Hydraulic Oils would result in:Provision of superior anti-wear protection.

  • Less downtime, reduced maintenance and longer component life.
  • Minimizing of harmful sludge and emulsions.
  • Longer oil service life, with reduced costs.

Details

Main Applications

  • Hydraulic transmissions and control systems in mobile equipment applications.
  • Machine tools and other pneumatic equipment lubricated through air line lubricators.
  • Hydraulic pump applications except for older designed silver-plated pumps.
  • Air compressors, speed reducers and chain drives.
  • Marine winches, hatch covers, steering gears, bow thrusters and automatic controls.
  • Mining equipment, including drills, loaders and shuttle cars.
