Atlas Copco DVS series dry rotary vane vacuum pumps

Atlas Copco has developed its new DVS vacuum pump series with a focus on sustainability, performance and ergonomics.

The DVS models are oil-free, dry rotary vane pumps that are designed to ensure emission-free, quiet operation and do not contaminate the processes.

The range is suitable for a wide range of applications, such as packaging and pneumatic conveying processes, medical systems and analytical equipment, as well as in pick-and-place for several automated industries.

The DVS models are designed to be quiet, low-wear and energy-saving and take up very little space.

They are suitable for applications in which high efficiency must be achieved at competitive costs. This is achieved on the one hand by the 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.

The efficient pump mechanism and the design ensure minimal wear, and this in turn leads to long maintenance intervals and easy servicing. In addition, the vacuum pumps are 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 series is also equipped with an inlet filter, non-return valve, exhaust silencer, a noise-containing canopy and an energy-efficient IE3 electric motor. It is available with a nominal suction volume flow of 5 to 140 m³/h and an ultimate vacuum of up to 120–150 mbar(a). For higher flow rates, the company recommends its dry claw vacuum pumps and systems of the DZS series.
