HiLobe series Roots pumps can be used for industrial vacuum applications such as electron-beam welding, vacuum furnaces or freeze drying. The compact pumps are of particular interest for fast evacuations (load-lock chambers or leak detection systems) and are also suitable for use in coating applications. Offering a wide nominal pumping speed range of 520-2,100 m3/h, the pumps can be precisely tailored to customer-specific requirements utilizing individual speed control. A new drive concept permits HiLobe to achieve approximately 20% shorter pump-down times than conventional Roots pumps. Rapid evacuation reduces costs and increases the efficiency of the production system.
