Anti wear hydraulic oil (ash free)
Product Introduction
The L-HM anti-wear hydraulic oil (ash free) series products are finely blended using advanced blending technology by adding various multifunctional additives to deeply refined base oil. Strict hydraulic pump and usage tests have shown that the oil not only has excellent anti-wear performance, but also has good antioxidant, anti emulsification, anti foaming, anti rust and other properties. It has good adaptability with nitrile rubber and other commonly used sealing materials and is suitable for precision hydraulic systems containing copper and silver components.
Product advantages
Excellent viscosity temperature performance ensures good lubrication, cooling, and sealing of the hydraulic system under working pressure and temperature changes.
Excellent extreme pressure and anti-wear performance, reducing equipment wear and effectively extending the service life of hydraulic pumps and other hydraulic components.
Excellent oxidation stability, slows down the decay rate of oil products, and prolongs the oil change cycle.
It has good compatibility with conventional sealing materials.

scope of application
Suitable for hydraulic systems in industries such as forestry, agriculture, and shipbuilding that require environmental protection. Especially suitable for precision hydraulic systems containing silver and copper components in the system.
precautions
Store indoors or under cover.
When storing outdoors, it should be placed at an angle to prevent rainwater from entering and prevent rusting of the iron bucket.
The storage temperature should be below 60 ℃ to avoid exposure to strong light and harsh cold environments.
Clean the equipment thoroughly when changing oil to avoid affecting its effectiveness.
