Product Features

Nitrogen Purge

Standard N₂ purge port. Injected nitrogen forms a gas barrier, isolating corrosive media and preventing contaminant buildup – protects rotors and pump body.

Oil‑Free & Clean

Dry‑running design, no oil in pump chamber. Oil‑vapor‑free exhaust – no contamination of process or environment. Ideal for semiconductor, pharma, food.

High Vacuum

PBG series: 1–2 Pa, PDG series: 5 Pa. Both outperform ordinary screw pumps – meet high‑vacuum needs from precision coating to chemical distillation.

Corrosion‑Resistant & Explosion‑Proof

Optional special coating and explosion‑proof motor for aggressive gases or flammable/explosive environments – suitable for chemical, pharma, lithium battery.

Water‑Cooled & Stable

Water‑cooled structure, high cooling efficiency, supports continuous operation. No need for compressed air – controlled operating cost.
