Gulf Harmony AW Plus
Premium quality anti-wear hydraulic oil
Product Description
Gulf Harmony AW Plus series are premium quality anti-wear hydraulic oils specially developed to meet the
requirements of the most demanding modern hydraulic systems in industrial and mobile service. These oils
are formulated with severely hydroprocessed Group II base oils and a carefully selected additive system to
satisfy the performance requirements of a wide range of hydraulic equipment subjected to high operating
pressures & temperatures and to provide extended drain intervals. They possess outstanding thermo-
oxidative stability, anti-wear property, rust & corrosion protection, water separation & air-release properties
and hydrolytic stability to prolong the equipment and oil life. 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 (MAG IAS, LLC) & Eaton (Vickers).
Features & Benefits
Outstanding thermo-oxidative stability reduces deposit formation, improves pump & valve
performance and allows extension of oil and filter change intervals
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 and sealing materials commonly used in hydraulic systems
Applications
Most demanding hydraulic systems subjected to high pressures and loads
Applications requiring extended oil change intervals
Hydraulic systems in industrial and mobile service employing gear, vane and piston pumps where
anti-wear hydraulic oils are recommended
Mobile hydraulic fluid power transmission systems and general machine lubrication
