Water Cooling Turbomolecular Vacuum Pump DFFZ250/2000PM-W
The DFFZ250/2000PM-W is a high-performance water-cooling turbomolecular vacuum pump engineered by BAOSI VACUUM for demanding industrial and scientific vacuum applications. Delivering 2000 L/s pumping speed with an ultimate pressure down to 6x10-7 Pa (CF flange), this pump combines grease-lubricated bearing technology with efficient water cooling for reliable long-term operation across semiconductor, coating, and research environments.
KEY FEATURES & BENEFITS
- Grease-Lubricated Bearings — Extended service intervals and simplified maintenance compared to oil-circulation systems, reducing total cost of ownership
- Efficient Water Cooling — Maintains stable operating temperature even under high gas load conditions, ensuring consistent vacuum performance during prolonged runs
- Flexible Any-Angle Installation — Mounts in horizontal, vertical, or inverted orientation without performance loss, adapting to tight equipment layouts
- Rapid Run-Up Under 7 Minutes — Reaches full 24000 rpm operating speed quickly, minimizing system downtime between process cycles
- Low Vibration Below 0.15 μm — Critical for sensitive applications such as electron microscopy, mass spectrometry, and precision coating where mechanical stability is essential
