Atlas Copco Develops Screw Vacuum Pump for Industrial Applications
Atlas Copco developed the dry screw vacuum pump DHS 3000 VSD+ specifically for massive flow industrial applications. As dry technology, it is well suited for paper processing, conveying technologies, pick-and-place applications in the food industry, and as a central vacuum system. Powered by a highly efficient IE4 motor with a patented asymmetrical rotor design, users benefit from energy savings of up to 50 percent compared to competitive products. The low-maintenance, compact vacuum pump has a pleasantly low noise level and also runs vibration-free.
An integrated, intelligent control system with frequency converter automatically adjusts the speed of the DHS 3000 VSD+ to the requirements, ensuring that the exact vacuum level required is delivered in each process section. This results in significantly lower energy consumption and reduced wear on all moving components. Overall, this also extends the maintenance intervals and service life of the vacuum pump. Companies that value stable performance and high process reliability and also need to reduce their energy costs will find the dry-running pump a robust, clean solution.
A wear-free gearbox ensures optimum power transmission from the motor to the screw.
“We have achieved a long service life for the gear wheels by using a cooled oil flow,” explains Carol Pignatelli, product manager from Atlas Copco. Because the DHS 3000 VSD+ does not use oil in any other way, there is no risk of oil emissions though carryover. “We have also equipped the DHS VSD+ with an air intake filter to protect operational process from dust and particles,” Carol Pignatelli continues.
The easy-to-use Elektronikon control system gives users a constant overview of the latest status updates on operating and downtimes, error and alarms.
“Atlas Copco supplies the DHS VSD+ as a complete plug-and-play unit that can be seamlessly and quickly integrated into any system,” concludes Pignatelli.
