Dalian No.3 seven star diffusion pump oil is a deep dewaxing lubricant, produce by vacuum molecular distillation, aluminum adsorption and film degassing processes,etc. This product has a low vapor pressure and a suitable chemical composition; with the ideal ultimate vacuum degree and fast pumping speed; also with the feature of very high thermal oxidation stability, can work for long time even in poor working condition.
No.3 diffusion pump oil can be used as a working fluid for various types of glass and metal diffusion pump, used in high vacuum distillation, vacuum metallurgy, electronics industry and the nuclear industry which has requirements to obtain a high vacuum environment systems.
No.3 diffusion pump oil pump can also be used as a working fluid for straight league vacuum pump.
