Oil booster vacuum pump NVBM
Oil booster vacuum pumps 2NVBM are designed for pumping down for pumping down air, gases, vapors and gas-vapor mixtures which are non-aggressive to the pumped fluid and construction materials in the inlet pressures range from 13,3 to 6,6·10-2 Pa ( from 1·10-1 to 5·10-4 Torr) and without containing condensed moisture and mechanical pollutions.
The pumps are used in combination with fore vacuum pumps as part of technological plants or systems in steady-state conditions.
In pumps is used original system of emergency air cooling which reduces stop time in case of need by several time.
Type of cooling is water cooling.
Booster pumps are mainly intended for pumping large quantities of gas from vacuum systems at pressures of from 10-1 до 10-4 Torr.
