Diaphragm Pumps for Air, Gases and Vapours Series LABOPORT® N 820 A_.18 Pumps LABOPORT®Diaphragm Vacuum Pumps Technical features: ■ Pure transferring and evacuation of gases ■ Highly compatible with vapours and condensation ■ Version for slightly aggressive or corrosive gases and vapours ■ Gastight, leakage rate approx. 6 x 10-3 mbar x l/s, not tested in serial production. Series N 820 diaphragm pumps are single-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.
