3.3 Function
DuoLine rotary vane vacuum pumps are two-stage, oil-sealed rotary positive displacement pumps for
use in coarse and medium vacuum. The vacuum pumps are equipped with a safety valve that vacuum
seals the vacuum chamber and simultaneously vents the vacuum pump when the pump is at a stand-
still. The rotary vane vacuum pump is available in the standard version with a conventional seal, or as
an M version with non-contact and wear-proof drive with magnetic coupling. The pump housing is her-
metically sealed.
