Rotary vane vacuum pump maintenance and oil change …
If an oil-sealed rotary pump is operated without an oil separation and return device, then it will be necessary to expect a certain amount of oil consumption, the extent of which will depend on the size of the pump and the nature of the process. In the worst case this can amount to about 2 cm3 for every cubic meter of air pumped.
