Double stage rotary vane vacuum pumps
2XZ rotary vane vacuum pumps are designed for the pumping of air
and other ordinary gases, as well as some condensable ones (e.g. water
vapor) by using a gas ballast. The pump must be fitted with appropriate
accessories if gas is rich in oxygen, explosive, corrosive to ferrous
metal, chemical reactive with vacuum pump oil. 2XZ pumps can be used
independently, or as a backing pump combined with other high vacuum
pump, such as diffusion pumps, Roots pumps, molecular pumps,etc. 2XZ
pumps are widely used in various industries like vacuum coating, vacuum
heat treatment,
electronics, semiconductors, illumination, food packing, refrigeration,
etc.
