HMC High-level Cleanness Anti-wear Hydraulic Oil

Product Introduction

The product is formulated utilizing high-quality paraffin-base base-oil and poly-functional additives of anti-oxygen, antirust, anti-wear and metal passivator in the super-clean environment through advanced technology.

Standard: Q/AHY 84-2007.

 

Application range

It is mainly applicable for the middle-high pressure hydraulic equipment in metallurgy, coal, power and construction, especially for the super-automatic hydraulic devices equipped with precise hydraulic elements (such as electro-hydraulic servo-valve, digital valve, and proportional valve) with strict requirement of cleanness.

 

Performance

²        Owing to its super-high viscosity index the product provides the prominent viscosity-temperature performance of the oil, so that it is suitable for the operating condition with great change of temperature.

²        Owing to its predominant EP anti-wear performance the product can slow down the abrasion of equipment and effectively prolong the service life of pump and system.

²        Owing to its excellent thermal stability and oxidation stability the product can slow down the decay rate of oil and prolong the oil change period.

²        It can ensure the system in sensitive, precise and stable operating owing to its eminent anti-foaming and air-releasing performance.

²        It ensures the stable and normal operation of the hydraulic device owing to its special cleanness performance.

 

Product variety

HMC 22, 32, 46, 68, 100 and 150 the six trademarks are provided.

 

Precautions

According to the provisions of oil consumption in equipments, the products with applicable quality and viscosity grade are selected; while special storage vessel should be adopted and prevent the interfusion of water, moisture, mechanical impurities and so on; meanwhile during operating you should maintain the cleanness of the oil tank, and clean the oil tank and oil path during oil change, so as to prevent the pollution. During application, the products with different types cannot be blended.
