DuoLine Two-Stage Rotary Vane Pumps

• Quiet operation • Improved water vapor tolerance • Clean and environmentally friendly

ComVac 2017. Pfeiffer Vacuum DuoLine two-stage high-performance rotary vane pumps cover all low and medium vacuum applications, achieving pumping speeds of 1.25 to 11 m^3/h. Applications range from mass spectrometry or optical coating to critical industrial applications such as drying processes, metallurgical processes or resin casting systems. If water vapor occurs during a process, a gas ballast is often used. The water vapor tolerance and the final pressure, obtainable with this gas ballast, are important criteria when selecting a rotary vane pump. For this reason, Pfeiffer Vacuum has significantly improved the water vapor tolerance of the pumps by using an optimized gas ballast system.

The DuoLine has a long service life and a pumping speed that is independent of the type of gas. Thanks to their compact design and optimized cooling, the pumps are very well suited for system integration.

The operating noises have been significantly reduced. For example, the Duo 1.6 reaches a value of 44 dB (A) at 50 Hz. Switchable motors that allow the connection voltage to be changed over between 115 V and 230 V are available for a wide range of applications.

Thanks to the reduced oil mist discharge, the innovative drive concept and the optional magnetic coupling, the rotary vane pumps are clean and environmentally friendly. The integrated, hydraulically controlled high-vacuum safety valve ensures high operational safety. An integrated connection point for oil return simplifies retrofitting of an oil mist filter.
