Gulf Harmony CME 68

High viscosity index hydraulic oil for Construction and Mining Equipment

Gulf Harmony CME series are supreme quality anti-wear hydraulic oils exclusively developed for construction and mining equipment in off highway applications requiring very high viscosity index oils to minimize the changes in viscosity even under wide temperature variation. These oils are formulated with severely hydroprocessed base oils, highly shear stable polymer and high performance additive system to meet the stringent requirements of modern hydraulic systems using high pressure high output pumps. Gulf Harmony CME exceeds the performance requirements of global industry standards like DIN 51524 Part 3 HVLP and majority of the international OEMs viz. Poclain, Hitachi, Eaton, Denison and others.

Features & Benefits

  • Exceptional anti-wear property results in longer pump life and reduced maintenance costs
  • Excellent shear stability ensures viscosity control over longer period of operation as demonstrated in the stringent Poclain Shear Stability Test – PH 904089920Q (VG 68)
  • Outstanding thermo-oxidative stability reduces deposit formation, improves pump & valve performance and allows extension of oil and filter change intervals
  • Very high viscosity index minimises change in viscosity of oil even under wide temperature variation thereby ensuring smooth functioning of hydraulic system
  • Excellent demulsibility helps in faster separation of water from oil and resists formation of emulsions
  • Compatible with multi-metals and sealing materials commonly used in hydraulic systems
  • Superior cleanliness ensures smooth & trouble-free operation of precision control hydraulic systems

Applications

  • Hydraulic systems of off-highway equipment like excavators, cranes and hydrostatic drives used in applications like construction, mining, agriculture, forestry, etc.
  • Hydraulic and power transmission systems subjected to a wide range of ambient & operating temperatures requiring long life super clean oils
