Series N838.3 diaphragm pumps are two-stage, dry- running devices used in a wide range of laboratory applicati- ons. They transfer and pump gases without contamination. The heart of these very compact pumps is a KNF structured diaphragm. This patented diaphragm was stress-optimized using the Finite Elements method. As a result, we were able to make the pumps smaller while increasing the service life of the diaphragm. The pumps are available in various versions differing in the materials which contact the media.
