Rotary vane vacuum pump (rotary vane pump for short) is an oil seal mechanical pump. Its working pressure in the range of 101325 ~ 1.33 × 10-2 (Pa) is a low vacuum pump. It may be used alone or as a pre-vacuum pump or other ultra-high vacuum pump. It has been widely used in metallurgy, machinery, military, electronics, chemicals, light industry, petroleum and pharmaceutical production and scientific research departments.

Rotary vane pumps can be sealed container extraction in the dry gas, with gas ballast if the device may also be a certain amount of pumping gas condensate.
