|KNF : Laboport Vacuum Pump|
Series N 816.3 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.
The pumps are available in various versions differing in the materials which contact the media.
100% oil-free transfer
Pure transfer, evacuation and compression
Version for slightly aggressive or corrosive gases and vapours
High level of gas tightness
