Product Features

Water Cooling

Adopts air‑cooled structure – no external cooling water, simplifies installation, avoids water quality issues. Runs on electricity only, ideal for water‑scarce or poor‑quality water areas.

Corrosion‑Resistant & Explosion‑Proof

Optional corrosion‑resistant coating (e.g., Ni‑P plating or PTFE spray) for harsh processes; explosion‑proof motor available for flammable/explosive environments.

High Ultimate Vacuum

Ultimate vacuum down to 5 Pa, pumping speed range 108‑1080 m³/h – strong, stable performance covers diverse process needs.

VFD Energy Saving

Upgradable to VFD motor – adjusts speed by actual load for energy‑efficient operation, reducing long‑term energy consumption.

Tough Conditions

Oil‑free design handles water vapor, dust, condensable gases – no contamination. Widely used in chemical, pharma, vacuum drying, etc.

Applications

Puyan screw vacuum pumps are widely used in:

Industrial Production

For electronics, metallurgy, semiconductor – handles water vapor and light dust, delivers clean vacuum.

Food Packaging

Oil‑free vacuum for continuous stretch film packaging, thermoforming – ensures food safety and shelf life.

Medical Equipment

Core of central suction systems – continuous, contamination‑free vacuum for operating rooms and wards.

Laboratory

For freeze drying, analytical instruments, molecular pump backing – completely oil‑free, no wear.

Central Vacuum System

Centralized supply in large plants (electronics, printing, pharma) – significant energy savings vs. distributed pumps.

Chemical & Pharmaceutical

Vacuum distillation, drying, solvent recovery – oil‑free design prevents contamination, meets GMP.
