Modern vacuum technology must convince users in their operations with features such as sustainability, performance and ergonomics. Atlas Copco has developed its new DVS vacuum pump series with a focus on this requirement profile. The DVS models are oil-free, dry rotary vane pumps that guarantee emission-free, quiet operation and do not contaminate the processes. They deliver high efficiency at competitive costs and suit for a wide range of applications: packaging and pneumatic conveying processes, medical systems and analytical equipment, as well as pick and place solutions.

In these work processes, the dry rotary vane pumps offer their users specific advantages: The DVS models are quiet, low-wear and energy-saving and take up very little space. They are predestined for applications in which high efficiency must be achieved at competitive costs. 

Proven functional principle, robust construction 

This is achieved on the one hand by the proven functional principle of the rotary vane pump and on the other hand by the use of robust materials. For example, a rotor with graphite blades rotates inside the DVS pumps. The centrifugal forces press the vanes against the inside of the housing wall and hermetically seal the chamber for a safe, uninterrupted operating vacuum as the high-quality graphite alloy generates vacuum with minimal friction losses. The efficient pump mechanism and the design ensure minimal wear – and this in turn leads to long maintenance intervals and easy servicing of the DVS. In addition, the vacuum pumps are thus designed for maximum operating times. The temperature management also contributes to this: To reduce the temperature of the discharged air, the exhaust air is passed through an air cooler.

The DVS series is also equipped with an inlet filter, non-return valve, exhaust silencer, a noise-containing canopy and an energy-efficient IE3 electric motor. The bottom line is that the interaction of these components forms the technological basis for a reliable pump with maximum vacuum performance and lower life cycle costs. The dry rotary vane vacuum pumps of the DVS series are available with a nominal suction volume flow of 5 m³/h to 140 m³/h and an ultimate vacuum of up to 120-150 mbar(a).
