Product description

Product Performance: Excellent extreme pressure and anti-wear properties reduce equipment wear, effectively extending the service life of pumps and systems; superior thermal and oxidation stability slows oil degradation and extends oil change intervals; excellent foam suppression and air release ensure sensitive, accurate, and stable transmission of static pressure; good demulsibility and filterability allow rapid separation of water from the oil, minimizing filter blockage and ensuring normal lubrication; good compatibility with various conventional sealing materials. Application Range: Suitable for different types of domestic or imported high-pressure and ultra-high-pressure hydraulic equipment equipped with vane pumps operating above 175 MPa and piston pumps operating above 35 MPa, such as high-pressure hydraulic systems in large engineering machinery like cranes, excavators, and dump trucks.

  • Excellent extreme pressure anti-wear performance, reduces equipment wear
  • Excellent thermal stability and oxidation resistance
  • Excellent foam resistance and air release property
  • Excellent demulsibility and filterability
