The UnoLine
TM
and DuoLine
TM
rotary vane pumps are single-stage, or two-stage, oil-sealed rotary posi-
tive displacement pumps with air cooling and pressure oil lubrication, for coarse and medium vacuum
applications. The vacuum pumps are equipped with a safety valve that vacuum seals the vacuum
chamber and simultaneously vents the pump when the pump is at a standstill. The 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 in the M version is hermetically sealed.
