DESCRIPTION:
Rotary Piston Vacuum Pump can not only be operated independently, but also be a backing pump when combined with Roots Vacuum Pump, Oil Boater Pump, Oil Diffusion Pump, The pump must be fitted with appropriate accessories if the exhausted gas is corrosive to ferrous metal, reactive with vacuum pump oil, or rich in vapor and dust.
