Duo 3 DC

Rotary vane pump with innovative DC drive. The ideal solution for automotive and analytical applications.

Unique 24 VD C rotary vane pump:

With the new Duo 3 DC, Pfeiffer Vacuum presents a 2-stage rotary vane pump that 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.

Adjustable pumping speed

The Duo 3 DC offers a pumping speed of 2.7 m³/h and an ultimate pressure of 3 · 10-3 hPa. Due to its innovative speed regulation, it is possible to achieve faster or slower pumping speeds.

Innovative product for the automotive industry

This pump is the solution for developers and suppliers of new, technologies in the automotive sector that need a vacuum pump with a 24 V power supply. The concepts currently being developed in this field will play an important role in the reduction of energy consumption and costs in vehicles. The Duo 3 DC generates the necessary low or fine vacuum to meet the specific requirements of this application.

Low noise level for analytical applications

The analytical industry also offers a wide range of applications for this pump. The quiet operation allows for an installation close to a work space where a 24 V power supply is often readily available.
