Successfully used for many years
Their strengths: quality, performance and reliability
Two-stage rotary vane pumps can operate in the pressure range between 100 hPa and a pressure approximately one decade above the ultimate pressure. The DuoVane series has vacuum performance from 5 to 20 m3/h. Our DuoLine pumps cover a wide range of pumping speeds from 1.3 to 300 m3/h, while the Pascal series offers superior vacuum performance in the 5 to 21 m3/h range.
With their outstanding features, including a long service life and pumping speed independent of gas type, these pumps are the perfect choice for a wide range of applications.

Pumping speed classes
Functional principle of Duo 6 and Duo 6 M by Pfeiffer Vacuum
Reliable vacuum generation without oil leaks
Our rotary vane pumps with magnetic coupling rely on innovative technology that eliminates oil leakage from shaft seals that are prone to wear. They are ideal for applications in analytical equipment, flywheel mass storage tanks and gas technology. With their compact design, they offer high pumping speed at low ultimate pressure. They also require little maintenance, as no regular replacement of shaft seals is necessary. This results in low operating costs, and the single-phase universal motor means they can be used worldwide. Our pumps with maintenance-free magnetic coupling are the reliable solution for efficient vacuum generation without oil leakage - in a compact format.

Rotary vane pump Duo 11 M ATEX
Pfeiffer Vacuum has developed the Duo 11 ATEX rotary vane pump in accordance with ATEX Directive 2014/34/EU specifically for processes in potentially explosive atmospheres or for conveying explosive gases and vapors. It satisfies the most stringent explosion protection requirements. The ATEX approval applies to both the indoor and outdoor areas of the pump. The pumps comply with equipment category 3G and temperature class T3. All gases up to and including explosion group IIC can be pumped.
Quiet and low-vibration rotary vane pumps
Our rotary vane pumps of the Instrumentation series are perfectly suited for demanding, vibration-sensitive applications in analytics and industry. With a pressurized oil lubrication, they allow operation even at high gas flow rates and still impress with an amazingly low sound pressure level of only 49 dB(A). These pumps are used in areas such as load-lock applications, electron microscopy, sterilization and leak detection. They are space-saving, offer high pumping speed with small dimensions, low ultimate pressure and are extremely reliable in operation. Their quiet operation makes them ideal for laboratories and similar environments, and they offer flexible integration with adjustable inlet and outlet ports.
