Two-stage Rotary Vane Pumps DuoLine™
Oil Leaks are Now a Thing of the Past!
DuoLine rotary vane pumps cover all applications in the low and medium vacuum range of up to 10-3 hPa. 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.
Thanks to their innovative drive concept, these pumps are hermetically sealed, making them clean and environmentally compatible. Because our magnetically coupled rotary vane pumps do not have radial shaft seals, there is no oil leak.
Rotary vane pump with innovative DC drive.
The ideal solution for automotive and analytical applications.
The Duo 3 DC was developed especially for 24 VDC applications. It is the only rotary vane pump in the market that operates in a temperature range from -20 °C to +60 °C. Due to its consumption of less than 100 W in continuous operation, it is extremely energy efficient. The brushless motor and optional magnetic coupling make the Duo 3 DC a very low-maintenance pump.
