Dual-stage rotary vane pumps with a pumping speed of 20 m3/h:
DuoLine rotary vane pumps cover all applications in the low and medium vacuum range of up to 20-3 mbar. These pumps offer reliable operation even for such critical industrial applications as drying processes, metallurgical processes or resin potting and casting systems – either as a standalone pump or as a backing pump in our roots pumping stations or turbo pumping stations
The use of a magnetic coupling minimizes maintenance requirements and leads to considerable cost savings per pump and maintenance interval.
Reliable, clean, low maintenance. Integrated safety and gas ballast valve. Various motor voltages afford worldwide employment. Contain no non-ferrous metals.
