Pfeiffer Vacuum


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.
