Vacuum pumps, booster steam-2NVBM-160-250 2NVBM, 2NVBM-400/6000 are intended for pumping of pressurized volume of air, gases, vapors and vapor mixtures, non-aggressive to the materials and construction of the pumped fluid inlet pressures in the range of 13.3 to 6 , 6 10-2 Pa (1 10-1 and 5 10-4 mm Hg) and does not contain condensed moisture and mechanical impurities.
The pumps are used in conjunction with a backing pump in the processing plants or systems in stationary conditions.
In the original design of the pumps used extra air cooling system that reduces repeatedly stop the pumps when required.
Cooling pumps - water. Booster pumps are mainly intended for pumping large quantities of gas from the vacuum systems at pressures of from 10-1 to 10-4 mmHg
