The Duo 125 and Duo 255 dependable two-stage rotary vane pumps from Pfeiffer Vacuum provide high pumping speeds between 120 and 250 m3/h in the low and medium vacuum ranges. These pumps are suitable for employment in high-vacuum pumping stations in combination with turbo pumps or as backing pumps for Roots pumps. Typical low and medium vacuum industrial applications include vacuum drying, metallurgy or coating. These pumps have compact diameters, provide high pumping speeds and operate at low noise levels. Thanks to the fact that their needle bearings are free of nonferrous metals, these pumps are extremely insensitive to dust, dirt and corrosive gases. An integrated pressure oil lubrication system improves their oil circulation and cooling.
