Product Description
Coomcool HMC 32 is refined from high quality paraffinic base oil by adding a variety of functional additives such as anti-wear, anti-oxidation, rust prevention, metal passivation, coagulation reduction, etc. In addition to the performance of high-quality anti-wear hydraulic oils, it is especially specified in the aspect of cleanliness.
Advantages
- Excellent extreme pressure anti-wear performance, slow down the wear of equipment, effectively extend the operating life of pumps and systems.
- Excellent thermal and oxidative stability, slowing down the rate of oil decay and extending the oil change period.
- Excellent anti-foaming and air releasing properties ensure the sensitive, accurate and smooth transmission of hydrostatic energy in the system.
- Good adaptability with all kinds of conventional sealing materials
- Special cleaning performance, not allowed to contain more than the limit of solid particles and other soluble dirt, to ensure smooth and normal work of the hydraulic device.
Applications
Suitable for metallurgy, coal, electric power, construction industry introduced or domestically produced medium and high-pressure hydraulic equipment, especially for highly automated hydraulic devices assembled with precision hydraulic components (such as electro-hydraulic servo valves, digital valves, proportional valves) that have strict requirements for cleanliness.
