ND-400R diffusion vacuum pump with water cooling system are designed for evacuating air, gases, vapors and gas-vapor mixtures which are non-aggressive to the pumped fluid and construction materials.
The ND-400R pump are designed to operate in stationary conditions in explosion-proof room.
It differ from NVDM series by extended range of operating pressures in the field of rough vacuum and by essentially improved outlet pressure.
The pump have cylindrical bead formed case inside of which are installed vapor line with set of nozzles, operating liquid heating system and oil deflector. High specefic characteristics are provided by optimally calculated construction of the ND-400R pump.
Oil diffusion pump ND-400R corresponds to the requirements of the specifications TU 3648-023-00218526-2002.
The pump ND-250R is produced with flanges according to industrial prevailing in the Soviet Union.
