Rotary Piston Vacuum Pump
Rotary piston valve vacuum pump is a variable capacity gas transmission pump, which has the advantages of high durability and large capacity. It is often used in large-scale vacuum equipment. It is suitable for vacuum smelting, vacuum drying, vacuum coating, vacuum impregnation and other vacuum operations. It can be used alone or as the front pump of other vacuum pumps, but it is not suitable for pumping from one vessel to another. When extracting excessive oxygen, explosive, corrosive to ferrous metals, chemical reaction to vacuum oil, water, dust and other gases, installations should be attached.
Industry Application
Rotary piston valve vacuum pump can be used as front pump in vacuum chamber, coating machine, drying and impregnation equipment.
