KNF Laboport Diaphragm vacuum pump N 820an.18

KNF LABOPORT Diaphragm vacuum pump N 820an.18 with silencer on the outlet.

The diaphragm pumps of the N 820 series are single-head dry-running pumps that are used in laboratories for a wide range of applications. They deliver and evacuate without contamination, i.e. the media are not contaminated. The heart of these very compact pumps is a KNF structural diaphragm. This patented diaphragm has been optimized using the finite element method. The result: smaller pump size and longer diaphragm service life. The pumps are offered in various material versions in the area in contact with the medium.
