Anti wear hydraulic oil
Product Introduction
The L-HM anti-wear hydraulic oil series products are made by finely blending deep refined base oil with various multifunctional additives using advanced blending technology. Strict hydraulic pump and usage tests have shown that the oil not only has excellent anti-wear performance, but also has good properties such as oxidation resistance, emulsification resistance, foam resistance, rust prevention, etc. It has good adaptability with nitrile rubber and other commonly used sealing materials, and its quality performance meets the requirements of GB11118.1-2011 L-HM specifications.
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.
Excellent anti foaming performance and air release value ensure that the hydraulic system can transmit static pressure energy sensitively, accurately, and smoothly.
Excellent filtration performance can reduce filter blockage to a certain extent, ensuring the normal operation of the hydraulic system.

scope of application
Mainly used in various types of medium and high hydraulic systems such as engineering machinery,construction machinery, mining machinery, steel rolling, plastic processing, and ocean going ships, as well as blade pumps and plunger pumps with steel copper friction pairs.
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.
