Oil-sealed rotary vane vacuum pumps are used in all areas of vacuum engineering. They are suitable for both industrial production and research and development. They can be used directly to generate vacuum or as pre-pumps in combination with lobe pumps or high vacuum pumps. Rotary vane vacuum pumps can be single or double stage. The final pressure range can be, depending on the model, between 0.5 mbar and 1•10 -4 mbar. The pumping speed can range from 1.5 m 3 /h to 13000 m 3 /h.
