Extreme pressure anti-wear Reduced Equipment Wear
Anti-Oxidation Extended Oil Drain Interval
Demulsibility Good filtration

Product Description

Excellent viscosity-temperature properties ensure proper lubrication, cooling, and sealing of hydraulic components under varying pressure and temperature conditions. Exceptional extreme pressure and anti-wear performance reduces equipment wear and effectively extends pump and system service life. Outstanding oxidation stability slows oil degradation and prolongs oil change intervals. Superior foam resistance and air release properties ensure sensitive, accurate, and stable transmission of static pressure. Excellent demulsibility and filterability allow rapid separation of water from the charged oil, minimizing filter clogging and ensuring normal lubrication. Ashless type offers better hydrolytic stability than zinc-type HM hydraulic oils. Good compatibility with various conventional sealing materials. Applications: mainly used for medium and high pressure hydraulic systems in aluminum profile equipment, engineering machinery, construction machinery, mining machinery, steel rolling, plastic processing, ocean-going vessels, etc., including vane pumps and piston pumps with steel-copper friction pairs. Also suitable for medium load industrial gear drives.

  • Excellent viscosity-temperature performance ensures reliable lubrication
