Diaphragm Pumps for Air, Gases and Vapours LABOPORT® Mini Diaphragm Vacuum Pumps ■ Pure transferring and evacuation of gases ■ Version for slightly aggressive or corrosive gases and vapours ■ High level of gas tightness. Series N 816.1.2 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. Material in contact with the pumped media Type/Order No. Pump head Diaphragm Valves Ultimate vacuum (mbar abs.) Permissible gas and ambient temperature +5 Mains Motor protection Power P1 Operating current Weight Dimensions With thermal switch and power fuse Motors with other voltages and frequencies on request. .45 = Pump with fine control valve and vacuum gauge Description Details Order No. Fine control valve with vacuum gauge_suction side_056547 KNF reserves the right to make changes.
