3.1 Function
UnoLine rotary vane vacuum pumps are single-stage, oil-sealed rotary displacement pumps with 2
pumping stages switched in parallel for applications 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 standstill. 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 hermetically sealed.
