ZINOL SUPER MARINE HYDRAULIC OIL series are supreme quality anti-wear hydraulic oils specially developed for applications subjected to wide range of temperature or where small viscosity change with fluctuating temperature is needed. They are formulated with severely hydroprocessed Group II base oils, a highly shear stable polymer and an advanced additive system to meet the stringent requirements of modern hydraulic systems using high pressure
high output pumps and critical requirement of other hydraulic system components such as high accuracy numerically controlled machine tools and those employing close clearance servo valves. Their outstanding thermo-oxidative stability and low & high temperature performance allows for extended service life.

  • Hydraulic and power transmission systems subjected to a wide range of ambient & operating temperatures
    Applications requiring extended oil change intervals.
  • Critical hydraulic systems such as high accuracy numerically controlled machine tools and those employing
    close clearance servo valves.
  • Hydraulic systems of excavators, cranes and hydrostatic drives subjected to most severe outdoor operating
    conditions.
  • Special rust & corrosion inhibitors protect multi-metallurgy components against negative effects of moisture presence in the system.
  • Rapid air release property minimizes chances of pump cavitations and thus prevents component damage, reduces vibration and maintains efficiency especially in modern hydraulic systems where sump sizes are becoming smaller
  • Outstanding thermo-oxidative stability reduces deposit formation, improves pump & valve performance and allows extension of oil and filter change intervals.
  • Extremely high viscosity index assures equipment protection at cold start-up temperatures and protects system components at high operating temperatures.
  • Exceptional anti-wear property results in fewer breakdowns, longer pump life and reduced maintenance costs.
