DV double stage rotary vane vacuum pump is the basic vacuum equipment of pumping gas from closed container, which take the advantages 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 range is 4-90m3/h, the user can adjust as needs.

Applications

DV pump 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.

Features  

· High ultimate vacuum, can continue work under high vacuum sates.

· Oil lubricated, exhaust oil vapor collection, preventing oil return device.
