Protective gas for the charging chamber of oil-free vertical vacuum pumps
Thread Content
For the production of carbon monoxide via pressure swing adsorption, an WLW-type oil-free vertical vacuum pump is used for evacuation. To ensure the purity of the carbon monoxide gas obtained, could carbon monoxide be introduced into the pumping chamber of the pump as a shielding gas?
