N 920 G diaphragm vacuum pump integrates with gas ballast valve

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

Tip When combined with VC 900 and the connection cable, the rotational speed is controlled in accordance with the requirements of the process.

Features
- 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
