Beijing Gonghua KS-3 mineral based diffusion pump oil for diffusion pump

Gonghua KS-3 diffusion pump oil Performance

Low saturated vapor pressure, narrow distillation range, high molecular weight and pumping speed.

※ When heated to its boiling point, the oil will eject in supersonic speed to create a vacuum environment rapidly.

※ Reasonable chemical compositions, perfect oxidation and thermal stability.

※ Low back-streaming rate, oil vapor will condense into new fluid as soon as it touches cold wall.

diffusion pump oil Application

Suitable for glass/metal diffusion pumps.

※ Applicable to vacuum distillation, vacuum metallurgy, vacuum coating, vacuum furnace etc.

※ Also be used as working fluid of diffusion pump in industries, such as electronics, aeronautics, nuclear etc.
