Busch R5 Oil-Lubricated Rotary Vane Vacuum Pump; Md# RA0250D

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.

A non-return valve prevents the pumped medium from flowing back into the process after the vacuum pump is switched off.
