NVDM High -Kuman diffusion steam oil pumps
The diffusion pumps of the NVDM are the most widely used pumps in industry to obtain high and ultra -high vacuum. The pumps are designed for pumping from hermetic volumes of air, gases, vapors and steam -gas mixtures that are not aggressive to the materials of the structure and working fluid and not containing drip moisture and mechanical pollution.
Pumps can be operated at ambient temperatures from 10 0 C to 45 0 C and the temperature of cooling water from 10 0 C to 20 0 p.
Pumps are used in conjunction with Forvacuum pumps as part of technological installations or systems in stationary conditions.
The pumps are not intended for use in fire-hazardous industries.
The largest exhaust pressure in pair pumps is much lower than atmospheric, therefore, preliminary vacuum is required for their operation.
