Atlas Copco AWS single-stage liquid ring pumps are engineered to deliver peak performance above 200 mbar(a), making them ideal for processes like filtration and wet conveying. With an ultimate vacuum capability of 30 mbar(a), they stand out as the top-tier choice for cyclic operations such as evacuation, impregnation, and sterilization.
For applications requiring sustained performance under 200 mbar(a), the AWD dual-stage pumps offer precision-tuned operation. Their two synchronized, series-connected pumping chambers ensure superior efficiency in continuous, mission-critical processes—including bottling, degassing, and solvent recovery—where reliability and consistency are non-negotiable.
Say goodbye to system complexity. Every AW liquid ring pump is available as a pre-engineered, plug-and-play module, ready to integrate seamlessly into once-through, partial recirculation, or total recovery configurations.
Backed by over 50 years of LRVP expertise and global field experience, Atlas Copco designs each module to match real-world demands. You get all the advantages of liquid ring technology—robustness, tolerance to wet and corrosive gases, low noise—while significantly reducing water and energy consumption.
Enhance your setup with easy-to-install standard accessories to complete your system quickly and efficiently.
When off-the-shelf isn’t enough, our engineering team steps in. For demanding or unique process requirements, we design fully customized vacuum systems built around Atlas Copco liquid ring pumps.
From material selection (cast iron, partial or full stainless steel) to precise configuration and multi-stage integration, our vacuum specialists tailor every detail to your operational specs. With expert support from concept to commissioning, the system adapts to you—not the other way around.
