Product Introduction:
HDM-VAC vacuum pump oil is usually prepared by refining mineral base oil and adding various additives such as anti-oxidation, anti-corrosion, anti-foaming and anti-wear, which is suitable for lubrication and sealing of front slide valve vacuum pump, belt rotary vane pump and Roots vacuum pump.
Application scope:
HDM-VAC vacuum pump oil is suitable for sealing and lubrication of positive displacement vacuum pump, and also for lubrication of gear transmission system of Roots vacuum pump.
Performance characteristics:
Good lubrication performance: it can provide good lubrication performance under high load conditions, which is very important for the long-term operation of vacuum pump.
Good sealing performance: lubricating films can be formed in various parts of the pump, thus improving the sealing performance of the pump.
Oxidation resistance: it can resist oxidation and maintain its performance, thus prolonging the service life of oil.
Good oil-water separation: it can be quickly separated from water, and the oil is not easy to emulsify.
