KNF double-diaphragm, oil-free pumps are designed for the safe transport and evacuation of costly, high purity, rare and/or dangerous gases.
In the patented double-diaphragm system, the primary diaphragm does the work, while the safety back-up diaphragm keeps gas from escaping in the event of a failure. Additionally, the pump is designed to prevent contamination from external influences.
These pumps are particularly well-suited for many chemical, nuclear, or process engineering applications, including:
- Gas sampling and monitoring
- Pulse tube and dilution refrigeration
- Helium liquefiers
