KNF LABOPORT® Chemically Resistant Vacuum Pumps

NEW TO JAVAC: Diaphragm Vacuum Pumps and Compressors for neutral, slightly aggressive and corrosive gases and vapours.

KNF's LABOPORT® pumps are single- or 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, KNF 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.
