Pumps

Series N811 diaphragm pumps are single-head, dry-running devices used in a wide range of laboratory applications. They transfer, evacuate and pump down without contamination. The core of these very compact pumps is a KNF structured diaphragm. This patented diaphragm was stress-optimized using the finite elements method. As a result, the pumps are smaller while increasing the service life of the diaphragm. The pumps are available in various versions differing with materials that come into contact with the media.
