"> "> ND is a new generation of high -bus -caring diffusion steam oil pumps
Pumps Vacuum diffusion steam-oil ND with air and gas are designed for pumping out air, gases , vapors and steam-gas mixtures that do not contain drip moisture and mechanical contaminants and are not aggressive to the materials and working fluid of the pump.
Pumps are designed to work in an explosion-proof room.
differ from the pumps of the NVDM series of the low vacuum, the workers' range of workers pressures and significantly improved exhaust pressure.
The parametric series of ND pumps (conditional passage diameter) 250, 250 400, 500, 630, 800 and 1000 mm. ND pumps have a cylindrical zygated case, inside which there are a steamboard with a nozzle system, a working fluid heating system and an oil refiner. The optimally calculated design of ND pumps provides high specific characteristics.
