Double-rotor vacuum pump NVD-200

Dvuhrotor vacuum pump NVD-200, is designed for pumping from hermetic vessels with pressure not more than 106,7 kPa (800 mm Hg.) air, non-aggressive to materials of construction fire-explosion-proof and non-toxic gases, vapours and vapour-gas mixtures, cleaned from dripping moisture and mechanical contaminants, with oxygen content not more than in air (21% by volume) under normal conditions, from atmospheric pressure to ultimate pressure. The pump is designed for pumping air, vapours and vapour-gas mixtures from one volume to another. The pump works only together with a forevacuum pump of not less than 20 m3/h. Type of climatic design UHL4. The pump is not designed for operation in fire-explosive production.
