LABOPORT N 820.3 AN.18 – Diaphragm Vacuum Pumps
Series N 820.3 diaphragm pumps are double-head, dry-running devices used in a wide range of laboratory applications. They transfer and pump down without contamination
Series N 820.3 diaphragm pumps are double-head, dry-running devices used in a wide range of laboratory applications.They transfer and pump down 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.
