With the new oil-free DSS scroll vacuum pump, Atlas Copco expands its range of dry industrial pumps. The robust, low-wear pump is particularly suitable for vacuum generation in the rough vacuum range. A key feature of the pump is its operating principle for gas handling. Inside the pump, two intermeshing, spiral-shaped screws are made of aluminum. One spiral screw is fixed, while the second one rotates to compress the gas inclusions.
The ergonomic vacuum pump is also characterized by low energy consumption, lower life cycle costs and user-friendly operation, according to the company. Due to the dry running of the pump, no oil changes are necessary. There is also no need to replace the exhaust filters, keeping the overall maintenance requirements relatively low. The removable front cover also simplifies access to the pump interior of the DSS scroll vacuum pump.
The new pump is particularly suited for applications in the pharmaceutical industry as well as in food packaging and processing, according to the company. The pump provides a stable vacuum at an atmospheric pressure of up to 1 mbar and maximum productivity at low to medium flow rates.
Another important feature of the DSS scroll vacuum pump is its complete freedom from oil. It does not use any oil for sealing or cooling, so there is no risk of oil contamination, according to the company.
