Designed for pumping air and gases, non-aggressive to gray cast iron, structural steel and mineral oil, and explosion-proof in the conditions of the flow part and gear reducer. It is used ONLY with a fore-vacuum pump and is the second stage of vacuum. It is used in the following processes: drying of transformers and other devices; impregnation of windings, cable, wood and other materials; distillation in metallurgy upon receipt of non-ferrous metals, as well as chemically pure substances in the chemical and pharmaceutical industries; freeze-drying of products, biologically active preparations, vaccines; melting, casting, alloying of metal alloys; sintering of fine-grained and powdery materials in powder metallurgy, during sintering, coking, in the manufacture of refractory products. The DVN pump consists of the pump itself, mounted on the foundation frame, and connected to it by means of an elastic finger coupling of the electric motor. Cooling of the pumps 2ДВН-500 - air, 2ДВН-1500 - water.
