Atlas Copco liquid ring vacuum pump engineered systems are built for complex duty applications such as vapor recovery, degassing, distillation, CPI, multiple vapor loads, and high capacities. These systems are custom designed with your specifications and are tailored to your application and process. We can design and engineer these systems for specific environments, with material certification, project-approved vendors, enhanced quality assurance and testing, all handled by our in-house contract management team. Our electrical engineers have experience designing and fitting control systems for intelligent pump management.
Our core vacuum pump ranges, AWC, AWS, AWD or AWL liquid ring vacuum pumps are available for both single and two-stage operations with capacities from 25-37500 m³/h (15 - 22072 cfm) and vacuum levels down to 30 mbar(a) (25 torr).

Once-Through Power Pack
Once through comprises a pump complete with electric motor, drive, and base frame. These systems are ideal where an ample supply of seal liquid is available, which can be subsequently discharged to drain. The liquid/gas mixture is discharged to drain through the discharge line.
Partial Recirculation
In this case, the liquid/gas mixture is separated in the discharge separator. The recovered service liquid is then mixed with fresh seal fluid to maintain a constant temperature in the pump. The excess liquid, equivalent to the make-up supply, goes in to the drain. The minimum amount of fresh make-up fluid is used to ensure cavitation-free operation at the required suction pressure. It offers typical water savings of 50% compared to once-through operation.
Total Recovery
Total recovery is a closed loop system that is used when the seal fluid is in short supply or when contamination may be a problem. To enable total recirculation of the seal liquid, the recovered liquid must be cooled prior to re-use. In this case, a heat exchanger is utilized between the discharge separator and the pump. It offers typical water savings of up to 95% compared to once-through operation.
