NP Turbine Oil R&O

Overview

NP Turbine Oil R&Ois a rust and oxidation inhibited oil and is ideally suited for the lubrication of high pressure steam turbines, governor hydraulic systems and other industrial applications where a lubricant with high oxidation stability is required. NP Turbine Oil R&O is manufactured using refined hydro-treated base oils which are designed to provide outstanding lubricating properties such as high oxidation stability, low volatility and elevated flash/fire points. NP Turbine Oil R&O is formulated using a carefully selected, well proven additive package designed to impart the following qualities in the finished lubricants:

  • Excellent thermal stability
  • Low copper activity 
  • Superior corrosion and rust protection
  • Exceptional demulsibility
  • Outstanding oxidative stability
  • Low foaming tendency

 
Benefits

The use of NP Turbine Oil R&O would result in:

  • Protection of bearings and other metallic parts against rust and corrosion (Oil was tested with both distilled water and synthetic seawater and passed both tests. Also achieved the highest rating for the copper corrosion test).
  • Reduction in the formation of acidic products that can lead to corrosion.
  • Reduces the formation of varnish, sludge and emulsions.
  • Better oil circulation and functioning of governors and oil relays.
  • Reduced loss of suction at the oil pump which is caused by entrained air with resulting loss of lubrication of critical components).
  • Long service life.

Details

MAIN APPLICATIONS

  • High-speed turbines.
  • Air compressors and blowers.
  • Certain hydraulic systems where an anti-wear lubricant is not required.
  • High speed gearing and oil lubricated bearings requiring a high quality R &O inhibited oil e.g. electric motor bearings.
