Atlas Copco – PAS Series

PAS open-body pump systems feature a centrifugal pump consisting of a semi-open impeller and a large separator. Air is separated from the liquid and drawn by the vacuum pump, enabling automatic priming. Moist prime pumps offer a portable and cost-effective solution, making them ideal for applications requiring uninterrupted flow. Dry prime pumps deliver high efficiency during extended use and are best suited for applications involving dry or intermittent flow. Both series ensure quick evacuation of air from the suction pipe, even in suction lifts several meters high, allowing pumping to begin seamlessly. Thanks to the semi-open impeller, both series are also suitable for pumping liquids containing suspended solids.
