Product Features

Wide Application

11 models available, pumping speed 300–5500 m³/h. Flexibly matches various large‑scale processes.

Energy Efficient

Industrial VFD + permanent magnet synchronous motor for precise control. 30%‑50% less energy than traditional technology – lower operating cost.

Reliable & Stable

Designed for demanding industries like metallurgy and chemicals. Ultimate vacuum ≤60 Pa meets core process requirements.

Easy Maintenance

No traditional wear parts – robust construction. Only oil change and filter cleaning needed – reduces downtime.

Low Noise

Advanced screw rotor technology plus noise‑reducing insulation and damping design – improves plant environment.

High Integration

“Plug‑and‑play” complete vacuum system with screw main unit and VFD – simplifies on‑site installation and commissioning.

Applications

Puyan oil lubricated screw vacuum pumps are widely used in:

Industrial Production

Vacuum adsorption, degassing, thermoforming, electronic component packaging – stable vacuum.

Medical Equipment

Clean, reliable vacuum for surgical suction, negative pressure drainage, medical dryers.

Laboratory

Supports vacuum drying ovens, rotary evaporators – low‑temperature drying, degassing, inert atmosphere.

Central Vacuum System

Single or parallel units generate vacuum distributed through piping to multiple terminals.

Chemical & Pharmaceutical

Vacuum distillation, solvent recovery, reactor evacuation, vacuum drying.

Food Packaging

Core component of vacuum packaging machines – quickly removes air to extend shelf life.
