L-HM high-pressure anti-wear hydraulic oil
L-HM32 / 46 / 68 / 100
Features excellent extreme pressure and anti-wear performance and thermal oxidation stability, effectively delaying oil aging and extending oil change intervals, while also offering good foam suppression and air release properties to ensure smooth and precise hydraulic system operation.
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
