100 horsepower kele (Clean) series vacuum pump oil made from high quality, low volatility, high quality base oil and additive modulation and become, for the vacuum pump lubrication. With high chemical stability, can resist oxidation and prevent subsequent silt and sediment formation. In all the required under the condition of continuous use, this is a basic feature. This makes oil such as viscosity and demulsibility preserved initial features, the service life of oil and thus to extend, has excellent resistance to corrosion and corrosion protection performance, including resistance to sea water and acid water protection.
