Product Description

Rotary vane vacuum pump 2NVR-5DM is designed for evacuating from sealed vessel air and nontoxic explosive and fire hazardous gases, which are non-aggressive to the pumped fluid and construction materials, vapors and gas-vapor mixtures which are precleared from condensed moisture and mechanical pollutions with oxygen content not more than in air (21 % by volume) at normal conditions. Pumping down goes from atmospheric to ultimate pressure under the condition that outlet pressure does not exceed atmospheric more than on 9,3 kPa (70 Torr)

Oil-sealed rotary vane pumps are used in all areas of vacuum technology in industry and research. They create medium vacuum or used as fore vacuum pumps in combination with roots blowers, diffusion, booster pumps and also with turbo molecular and cryo pumps.

Rotary vane vacuum pump 2NVR-5DM corresponds to the requirements of the specifications
TU 3648-006-00218526-2002.
The vacuum unit AVD-50/5 is produced on the base of rotary vane pump 2NVR-250D in combination with roots blower NVD-200.
2NVR-5DM is the first domestic pump which has built-in shut-off and inlet valves. The pump is equipped with a gas ballast which prevents condensation of water vapor during evacuation of vapors and gas-vapor mixtures.
