The performance characteristics of | ||
Technical performance | Use effect | |
Excellent wear resistance | Effectively reduce the wear of hydraulic pump, prolong the service life of pump and system | |
Excellent rust resistance and corrosion resistance | Provide protection for equipment in humid environment | |
Excel lentwater separation performance | The water in the oil can be separated quickly, which can effectively reduce the damage to the pump and ensure the performance of the oil | |
Excellent filtration performance | Reduces the fouling in the pipeline, prevents the blockage of the filtration system, and reduces the frequency of filter replacement | |
Good rubber adaptability | Effectively protect sealing material to prevent leakage |
