Product Introduction:
HDM-ZS ester vacuum pump oil is a kind of high-performance lubricating oil, and its main component is synthetic ester compounds. It has excellent lubricity, oxidation resistance, wear resistance, low-temperature fluidity and compatibility with various refrigerants. It is especially suitable for vacuum systems in the manufacturing prcess of refrigeration equipment such as air conditioners and refrigerators, as well as for various high-temperature and high-speed mechanical pumps. This product is also an environmentally friendly product, and its biodegradability is over 95%.
Performance characteristics:
It is characterized by high viscosity index and high flash point.
Soluble with R134a, R113, R502, R22, R1426, R404a and other refrigerants.
It has excellent oxidation stability and thermal stability, which greatly improves the service life of oil products.
It belongs to environmental protection products, and its biodegradability is more than 95%.
Application scope:
HDM-ZS ester vacuum pump oil is suitable for vacuum technical field: dry screw pump, Roots pump, rotary vane pump, etc. It can run stably in high vacuum environment, reducing the damage and maintenance cost of equipment.
