Scope
1.Widely used in metallurgy, chemical, petroleum, medical, pharmaceutical, semiconductor, food, atomic energy, textile industries, as well as research institutions, universities and enterprises for R&D, production and teaching.
2.Constructed from ferrous metals with precision design, the pump operates in oil. Not suitable for:
2-1.Gases with high oxygen, toxicity, explosiveness, or corrosive to ferrous metals
2-2.Gases reactive with vacuum oil
2-3.Compressor or transfer pump applications：Gas ballast-equipped models handle limited condensable gases
3.Capabilities:
3-1.Direct vacuum below 10⁻³ Torr
3-2.Front-stage pump for higher vacuum (≥10⁻³ Torr) with booster systems
4.Operating environment:
Temperature ≥5℃, humidity ≤90%
5.Optional configuration:
Pair with vacuum booster (e.g., Roots pump) as front-stage to form vacuum unit for enhanced vacuum performance.
