VD series is a direct-drive oil rotary pump with high efficiency (IE3) multi-voltage motor fully developed by ULVAC. This dual stage rotary vane mechanical vacuum achieves lower ultimate pressure. Design optimization realized quiet operation and so this pump is suitable for a wide range of applications.
Features
- Optimized design for quite operations
- Easy maintenance
- Forced oil circulation system ensures stable pumping speed below atmospheric pressure
- Totally enclosed fan cooled 3 phase AC motor
Applications
- Evaporation, sputtering, ion plating
- Analysis devices, leak test equipment
- Gas substitution/supply, vacuum insulation
- Vacuum drying, freeze-drying, vacuum degassing, vacuum packing, vacuum chuck, vacuum molding
