2XZ-15B Core Parameters
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:
Industrial Production
Evaporation and sputtering coating systems – clean high vacuum for uniform film layers.
Laboratory Analytical Instruments
Mass spectrometers, electron microscopes, surface analyzers – stable high vacuum for measurement accuracy.
Chemical & Pharmaceutical
Vacuum distillation, solvent recovery, vacuum drying – handles condensable vapors.
Refrigeration Equipment
Evacuates refrigerant lines and compressors – removes moisture and non‑condensable gases to prevent ice blockage.
Vacuum Metallurgy
Vacuum melting, degassing, sintering – used as backing pump or main pump.
Vacuum Impregnation
For capacitors, transformers, motor windings – removes moisture and gas from insulation, improves performance.
