Proven Solutions for Roots Pumping Stations! More Advice. More Competence. More than just Vacuum. What’s the added value for you? Just imagine you have to evacuate a volume of 630 cubic meters. This is equivalent to the cubical content of a singlefamily home. Systems with chambers of this size are being built today for electron-beam welding of components with weights of up to 50 tons and dimensions of up to 12·6·5 meters. With a 40-kilowatt beam, it is possible to achieve weld depths of up to 100 millimeters in steel and 150 millimeters in aluminum. To do this necessitates a vacuum of...

Now things are getting exciting! Our engineers have developed the following solution: A maximum of 30 minutes has been stipulated for evacuating from 1,000 to 5 ·10-2 millibars. To achieve this, four large vacuum pumping stations are employed, each consisting of one rotary vane pump and two large Roots pumps. The maximum combined pumping speed of all pumping stations totals 40,000 cubic meters per hour at a pressure of 0.1 milli bar. In the high-vacuum range, it is necessary to do more than just evacuate the volume. Both the vapors produced in connection with the welding process as well as...

For applications requiring ultimate pressures of up to 5 -10-4 mbar These are classical pumping stations for a broad range of applications in the coating segment. The pumping stations are especially suitable as backing stations for high-vacuum pumps. Possible applications for these pumping stations include the application of anti-wear coatings on lathe tools and drills, decorative coatings for gemstones, as well as optical coatings for eyeglass lenses or architectural glass. A further field of application consists of metallurgy, where hardening or nitriding enables the properties of the...
