Gulf Harmony ZF HVI Plus Super Clean 68
Supreme quality ashless high viscosity index super clean hydraulic oil for extreme temperature ranges
Gulf Harmony ZF-HVI Plus Super Clean series are supreme quality anti-wear hydraulic oils specially developed for applications requiring super clean oils and 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 ash-less additive system to provide reduced environmental impact in case of an accidental release into the environment. They 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. They provide excellent anti-wear property, rust & corrosion protection, water separation & air-release properties and hydrolytic stability to reduce breakdowns and help improve production capacity.
They are available in ISO viscosity grades 32, 46, 68 & 100 and exceed the performance requirements of global industry standards viz. DIN 51524 Part 3 HVLP, AFNOR NFE 48-603 (HV) & ISO 11158 HV and majority of the international OEMs viz. Poclain, Hitachi, FIVES CINCINNATI (Former MAG IAS, LLC), Eaton (Vickers) and Denison.

Features & Benefits
- 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
- Excellent shear stability minimises viscosity loss over time and exhibits “stay-in-grade” performance under high shear conditions
- Exceptional anti-wear property results in fewer breakdowns, longer pump life and reduced costs
- Advanced ashless additive technology reduces environmental impact in case of accidental spillage or leakage
- Superior cleanliness of this oil ensures smooth & trouble-free operation of precision control hydraulic systems employing close clearance servo valves
- Excellent demulsibility helps in faster separation of water from oil and resists formation of emulsions
- Special rust & corrosion inhibitors protect multi-metallurgy components against negative effects of moisture presence in the system
- Rapid air release property minimises chances of pump cavitation and thus prevents component damage, reduces vibration and maintains efficiency especially in modern hydraulic systems where sump sizes are becoming smaller
- Offers long term hydrolytic stability and yellow metal compatibility in presence of water
- Compatible with multi-metals and sealing materials commonly used in hydraulic systems
Applications
- Hydraulic and power transmission systems subjected to a wide range of ambient & operating temperatures requiring super clean oils even in environmentally sensitive applications
- 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
- Hydraulic systems operating under high pressures and requiring high degree of load carrying capability and anti-wear protection
