Busch R5 Oil Lubricated Rotary Vane Vacuum Pump

Busch R5 Oil Lubricated Rotary Vane Vacuum Pump is known for its robustness and reliability. You can always rely on the R5 – whether used intermittently or around the clock. A wide range of sizes, design options and accessories ensures that the R5 is the perfect match for many processes. Maintenance can easily be carried out by the operator. Apart from changing oil and filters at regular service intervals, no further maintenance is required. Operating Principle R5 rotary vane technology is synonymous with a robust and functional construction. In a cylindrical housing, a rotor with three vanes is mounted eccentrically. Due to centrifugal force, these vanes slide out and form chambers between themselves and the housing. The pumped medium is trapped inside these three chambers. During further rotation, their volume is constantly reduced. Thereby, the pumped medium is compressed and transported to the outlet. R5 vacuum pumps operate with recirculating oil lubrication. A downstream oil separator segregates sealing oil and pumped medium for efficient reuse of oil.
