WIN400 Dry Screw Vacuum Pump
- Commodity name： WIN400 Dry Screw Vacuum Pump
- Product Description
-
Small air-cooled dry screw vacuum pump (pumping speed: 18–80 cubic meters/hour)
Performance Features
- Advanced technology: Leveraging next-generation composite variable-pitch screw technology
- Environmental Protection: The flow-through section features an oil- and water-free structural design, ensuring a clean vacuum while allowing the extracted materials to be recycled and reused.
- Energy Efficiency: Utilizing variable-pitch energy-saving technology reduces energy consumption by up to 30%.
- Chemically Resistant: The pump chamber features a corrosion-resistant nano-ceramic coating, while the O-rings are made from fluororubber. (Optional corrosion-resistant version available: Flow-through components treated with nano-ceramic, and seals can be upgraded to highly durable materials such as perfluoroether or EPDM.)
- Air cooling: Features an air-cooling design, eliminating the need for cooling water and offering convenient installation.
- Energy-efficient: The machine boasts stable performance, simple operation, and a maintenance cycle of over 10,000 hours.
- Maximum vacuum: ≤1 Pa (measured at the inlet)
- Work area width: Operates continuously from atmospheric pressure up to ultimate vacuum.
- Reliable sealing: A mechanical seal combined with a lip seal design ensures enhanced reliability, smooth exhaust flow, and excellent liquid-handling capabilities.
- Lightweight: Made from a new alloy material, it’s significantly lighter.
- Wide power supply compatibility: Available with 3-phase 380V / 3-phase 220V / single-phase 220V power options, enabling broader application scenarios.
