Product Features

High Ultimate Vacuum

Two‑stage design, ultimate vacuum down to 0.06 Pa. Ideal for distillation, analytical instrumentation, etc.

Compact & Lightweight

Small footprint, light weight, easy start, low noise – simple to install and move.

Gas Ballast Valve

Prevents condensation of water vapor and other condensable gases, avoids oil emulsification, extends oil life. Maintains high ultimate vacuum even with gas ballast open.

Anti‑Backflow

Prevents oil backflow – no leakage, no contamination. Suitable for cleanliness‑sensitive environments.

Versatile Application

Can be used alone or as backing pump for Roots, diffusion, molecular pumps, etc.

Applications

Puyan two‑stage rotary vane vacuum pumps are widely used in:

Vacuum coating

Industrial Production

Evaporation and sputtering coating systems – clean high vacuum for uniform film layers.

Laboratory analytical instruments

Laboratory Analytical Instruments

Mass spectrometers, electron microscopes, surface analyzers – stable high vacuum for measurement accuracy.

Chemical & pharmaceutical

Chemical & Pharmaceutical

Vacuum distillation, solvent recovery, vacuum drying – handles condensable vapors.

Refrigeration equipment

Refrigeration Equipment

Evacuates refrigerant lines and compressors – removes moisture and non‑condensable gases to prevent ice blockage.

Vacuum metallurgy

Vacuum Metallurgy

Vacuum melting, degassing, sintering – used as backing pump or main pump.

Vacuum impregnation

Vacuum Impregnation

For capacitors, transformers, motor windings – removes moisture and gas from insulation, improves performance.
