Double Stage Piston Vacuum Pump

The two-stage piston vacuum pump series is suitable for suction of air and other general gases. When using air ballast, the pump can suck a small amount of condensable gases (such as water vapor). Additional devices should be used when pumping gases with excessive oxygen content, explosive, corrosive to ferrous metals, and chemical reaction to vacuum oil. This type of pump can be used alone or as a pre pump for diffuser pumps, roots pumps and other high vacuum pumps. The pump is widely used in vacuum coating, vacuum heat treatment, vacuum impregnation, vacuum sintering, vacuum metallurgy, vacuum drying, molecular distillation.
