With the introduction of the magnetically coupled DuoLine,
Pfeiffer Vacuum gained a key technology edge in the field
of two-stage rotary vane pumps back in 1996. Successful
development work has enabled this technology edge to be
further broadened. With the PentaLine series, it has been
possible to offer backing pumps with pumping speeds of
20 to 35 m3/h that provide convincing, environmentally
friendly cost-effectiveness. The ability to slash energy costs
by around 30 % makes this a highly attractive vacuum
solution by comparison with conventional rotary vane
pumps equipped with asynchronous motors.
