Vacuum Pumps

VACUUM PUMPS of the ДВН series

Are designed for pumping out air and gases non-aggressive to grey cast iron, structural steel and mineral oil, and explosion-proof in the flow passage and reduction gear. The pumps are to be used ONLY with a fore pump and are the second stage of rarefaction.
The vacuum pumps find application in the following technological processes:
-         drying of transformers and other devices;
-         impregnation of winding, cable, wood and other materials;
-         distillation in the production of non-ferrous metals in metallurgy, and pure substances in chemical and pharmaceutical industries;
-         sublimation drying of products, bioactive preparations, vaccines;
-         melting, casting, doping of metal alloys;
-         sintering of fine-grained and powdery materials in powder metallurgy, in agglomeration, coking process, in the production of refractory products.

Pump ДВН consists of a pump proper mounted onto the foundation frame and an electric motor attached to it with the help of a flexible pin coupling. Pump 2ДВН-500 is cooled by air, while pump 2ДВН-1500 is cooled by water.
