DV Oil Lubrication Two Stages Rotary Vane Vacuum Pump:
DV Double Stage Rotary Vane Vacuum Pump is basic vacuum equipment of pumping gas from closed container, which take the advantage of compact structure, small size, light weight, low noise, low vibration etc. It not only independent use, but as the backing pump of the booster pump, diffusion pump, molecular pump. Pumping speed from 4-90m3/h, can choose as users' needs.
Applications:
Widely used in vacuum smelting of metallurgy, machinery, electronics, semiconductors, refrigeration, chemical, petroleum, medicine, vacuum coating, vacuum heat treatment, vacuum drying, meteorological analysis, physical and chemical test.
