Description

Diffusion high-vacuum pump ND-250 is designed for pumping out of hermetic volumes of air, gases, vapours and vapour-gas mixtures which are not aggressive to materials of construction and working fluid and do not contain dripping moisture and mechanical contaminants. The ND-250 diffusion high-vacuum pump is used in conjunction with a forevacuum pump, the speed of action of the forevacuum pump is not less than 40 m3/h.

Type of climatic execution UHL4, the pump is not intended for operation in fire-explosive production. Flange type ISO-K
