NP Hydraulic Oils HV

Overview

The NP Hydraulic Oils HV range of lubricants are premium grade lubricants designed to provide outstanding lubrication of vane and piston pumps, actuators, control valves and hydraulic systems. NP Hydraulic Oils HV are manufactured from high viscosity-index 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 HV result in

  • Anti-wear performance
  • Corrosion protection
  • Anti-foam properties
  • Oxidation/thermal stability
  • Filterability
  • Demulsibility

Benefits

The use of NP Hydraulic Oil HVwould result in:

  • Less downtime, reduced maintenance and longer component life.
  • Minimizing of harmful sludge and emulsions.
  • Longer oil service life, with reduced costs.
  • Provision of superior anti-wear protection even under increasing bulk temperatures.

Details

Main Applications

  • Hydraulic transmissions and control systems in mobile, marine and industrial applications.
  • Systems operating under hot conditions e.g. plastic injection molding machines.
  • Systems that are subjected to wide variations of ambient temperature, or where a narrow viscosity span is required. It is not designed for use in older design silver-plated pumps (e.g. old Lucas Pumps).
