High Suction Speeds at Low Absolute Pressures
KNF’s popular N 920 G diaphragm vacuum pump is designed to support a wide range of laboratory applications such as centrifugal concentration, gel drying, degassing, desiccation, and more.
Latest KNF technical innovations, including a special diaphragm stabilization system, makes this compact pump well-suited for applications requiring high suction speeds at low absolute pressures.
Combination Possibilities
- N 920 G Diaphragm Vacuum Pump
- C 900 Chiller
- VC 900 Vacuum Controller
- RC 600 Rotary Evaporator
Tip When combined with VC 900 and the connection cable, the rotational speed is controlled in accordance with the requirements of the process.
-
- Integrated rotational speed control enables pumping capacity to be easily adapted manually to process requirements
- Integrated gas ballast valve
- Environmentally friendly
- Ideal for aggressive/corrosive gases and vapors
- Maintenance free
- 100% Oil-free operation
- Pure transferring and evacuation of gases
- High suction speed, particularly in the low vacuum range
