Atlas Copco’s PAS pumps
Atlas Copco’s PAS pumps
The PAS pumps are intended for high-performance dewatering in tough conditions and focus on high fuel efficiency in a wide range of sizes. The expanded range is designed for multiple applications, from dewatering on construction and mining sites to solids removal, drainage and even emergency situations involving flooding and shipping.
 

The new pumps offer performance levels from 105 m3/h to 630 m3/h, and discharge size ranging from 3 in to 8 in. The PAS open-frame system comprises a centrifugal pump, semi-open impeller and a large separator. This enables air to be separated from the liquid and sucked by the vacuum pump, making automatic priming possible. Even with suction heights of several metres, the rapid evacuation of air from the suction pipe ensures fast activation of pumping.
