An All-Around Pump with a Double-Diaphragm

An optional water-cooling system can be installed to enhance non-Ex versions to handle ambient and media temperatures of up to 60 degrees Celsius. Even more secure with a double diaphragm: The versatile N 630 pump series upholds its excellent reputation. A total of six new versions offer a major expansion to the diaphragm gas pump’s range of uses. The series’ key properties – robustness, durability and long service life – are now supplemented by a greater degree of safety. The N 630 is a true all-rounder within the KNF modular system. The oil-free diaphragm gas pump transfers and compresses gases and vapors, and generates a vacuum without contaminating the media. Therefore, it finds use in many applications in research, energy technology, process manufacturing, and the chemical and petrochemical industry. Continuous expansion to keep pace with market needs KNF continues to expand the N 630 pump series to keep pace with the broad spectrum of applications. Six new models with double diaphragms are geared towards users who work with valuable and hazardous gases. Even if the working diaphragm should fail, no gas will escape, thanks to the safety diaphragm installed underneath. All of the new models can be equipped with an external sensor to monitor the state of the working diaphragm. New N 630 expansion convinces with high gas tightness Based on actual field data, pump gas tightness can be modified from the normal 5 × 10-5 mbar × l/sec to an increased 6 × 10-6 mbar × l/sec. The high gas tightness of N 630 is particularly well suited for transporting helium and its rare/costly isotopes. The N 630 with a double diaphragm securely transfers the uncontaminated noble gas for recycling. This pump is also particularly useful for cryostat applications, where it reliably compresses the helium cooling medium.
