Pfeiffer Vacuum GmbH

With its DuoLine and Pascal two-stage rotary vane pumps, Pfeiffer Vacuum has offered two very successful ranges for many years now. Their long life and pumping speed, irrespective of the gas used, are the outstanding properties of these pumps. Two-stage rotary vane pumps can be used in the pressure range between 100 hPa and a pressure roughly a decade above the final pressure. Pumps belonging to the DuoLine series cover a pumping speed range of 1.3 to 300 m3/h. In the 5 - 21 m3/h range, Pfeiffer Vacuum also offers the Pascal series as products with superior vacuum performance. Pumps in the Pascal range are principally used as standalone pumps. Both series are available in a standard version with a shaft seal for use in straightforward applications. The Pascal series is additionally available as an instrumentation version for more sophisticated applications, such as frequent cyclical pump-down processes (load locks). There are various corrosive versions available for pumping aggressive media. DuoLine pumps with a magnetic coupling dispense with the need for shaft seal maintenance.

Through its compactness, the diaphragm pump from Pfeiffer Vacuum is ideal for integration in increasingly small analytical systems and turbopumping stations. Beginning with a pumping speed of 0.25 m3 per hour, you can choose from a wide selection of pumps. The strongest of these vacuum pumps manages a pumping speed of max. 4.3 m3/h. The benefits of the diaphragm pump from Pfeiffer Vacuum are numerous, the efficiency and reliability unique.

This line of dry screw pumps is optimally suited for applications in low and medium vacuum. It is designed not only for industrial use but also for coating applications. HeptaDry is the ideal solution for all areas which require oil-free vacuum. Pumping speeds ranging from 100 to 630 m3/h are achieved by this product series.
