HFV--K Series Diffusion Pump Oil(Mineral)

High flash point and high viscosity index,vacuum degree will not be reduced at hight
Performance
1. Low saturated vapor pressure,narrow distillaiton range,high molecular weight and pumping speed.
2. When heated to its boiling piont,the oil will eject in supersonic.
3. Reasonable chemical compositions,perfect oxidation and thermal stability.
4. Low back-streaming rate,oil vapor will condense into new fluid as soon as it touches cold wall.

Application
1. Suitable for vapor diffusion pumps,it is available according to the final pressure only.
2. Applicable to vacuum distillation,vacuum metallurgy,vacuum coating,vacuum fumace,and etc.
3. Also be used as working fluid of diffusion pump in industries,msuch as electronics,nuclear and etc.
