Name: HFV-K Series Diffusion Pump Oil Model: HFV-K Brief: Low saturated vapor pressure,narrow distillation range,high molecular weight
and pumping speed.
详细介绍
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.
Application
※ Suitable for vapor diffusion pumps,it is available according to the final pressure only.
※ Applicable to vacuum distillation,vacuum metallurgy,vacuum coating, vacuum furnace, and etc.
※ Also be used as working fluid of diffusion pump in industries,such as electronics, aeronautics,
nuclear and etc.
