Gulf Harmony ZF 46

High performance ashless anti-wear hydraulic oil

Gulf Harmony ZF series are high performance ashless anti-wear hydraulic oils developed to provide excellent performance in hydraulic systems operating under moderate to severe conditions. They are formulated with an advanced ashless anti-wear technology and select base oils to provide reduced environmental impact in case of an accidental release into the environment. They exhibit excellent anti-wear property, thermo-oxidative stability, foam control and water separation properties. They are available in ISO 10 through ISO 100 viscosity grades and exceed the performance requirements of global industry standards viz. DIN 51524 Part 2-HLP, AFNOR NFE 48-603 (HM) & ISO 11158 HM and majority of the international OEMs viz. Denison, FIVES CINCINNATI (Former MAG IAS, LLC) and Eaton (Vickers).

Features & Benefits

  • Excellent thermo-oxidative stability controls the formation of sludge & varnish and improves oil life
  • Exceptional anti-wear property results in longer pump and component life and reduces costs
  • Superior demulsibility helps in faster separation of water from oil and resists formation of emulsions
  • Advanced ashless additive technology reduces environmental impact in case of accidental spillage
  • Special rust & corrosion inhibitors protect multi-metallurgy components even in presence of moisture
  • Rapid air release property minimises chances of pump cavitation leading to trouble free operations
  • Compatible with multi-metals and sealing materials commonly used in hydraulic systems

Applications

  • Hydraulic systems operating under moderate to severe conditions in mobile and industrial service even in environmentally sensitive applications
  • Mobile hydraulic fluid power transmission systems and general machine lubrication
  • Older design hydraulic pumps containing silver or silver-plated parts
