Description:

Gulf Harmony HVI Plus 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. 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 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, MAG IAS, LLC, Eaton & Denison.

Features & Benefits:

• Outstanding thermo-oxidative stability reduces deposit formation, improves pump performance and gives extended oil and filter change intervals
• Extremely high viscosity index assures equipment protection at cold start-up temperatures as well as at high operating temperatures
• Exceptional anti-wear property results in fewer breakdowns, longer pump life and reduced maintenance costs
• 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 & most sealing materials used in hydraulic systems

Applications:

• 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
• Hydraulic systems operating under high pressures and requiring high degree of load carrying capability and anti-wear protection
