Atlas Copco has developed the DHS 3000 VSD+ dry screw vacuum pump for high-flow industrial applications, with use cases including paper processing, conveying systems, food industry pick-and-place operations and central vacuum systems.
The pump uses dry technology, eliminating oil from the compression chamber, and is driven by an IE4 motor with an asymmetrical rotor design. Atlas Copco says the system can deliver energy savings compared with conventional vacuum technologies, depending on application and operating conditions.
The DHS 3000 VSD+ incorporates an integrated control system with a frequency converter, allowing the pump to adjust speed based on demand and maintain the required vacuum level across different process stages. This approach is designed to reduce energy consumption and limit wear on moving components.
The system is also intended to extend service intervals through controlled operation and reduced mechanical load.
Carol Pignatelli, product manager at Atlas Copco, says the design focuses on durability and clean operation.
“We have achieved a long service life for the gear wheels by using a cooled oil flow,” Pignatelli says.
Because the pump does not use oil in the compression process, the risk of oil carryover is removed, while an inlet filter is used to protect against dust and particles in the process stream.
The unit is housed within a noise-reducing enclosure and is designed to operate with low vibration, supporting installation in production environments where noise and stability are considerations.
The DHS 3000 VSD+ is supplied as a plug-and-play system, with the Elektronikon control platform providing operational data including running hours, downtime and alarm status.
“Atlas Copco supplies the DHS VSD+ as a complete plug-and-play unit that can be seamlessly and quickly integrated into any system,” Pignatelli says.
Key features of the DHS 3000 VSD+ include variable speed operation, compact footprint, dust protection and integration with preventive maintenance planning.
