The expanded PAS 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 PAS open-frame system includes both wet and dry prime options, and the modular design allows many different configurations.
They provide a wide range of sizes, with performance levels from 105m³/hour to 630m³/hour, and discharge size ranging from 3ins to 8ins.
The PAS open-frame system comprises a centrifugal pump, semi-open impeller and a large separator, which enables air to be separated from the liquid and sucked by the vacuum pump, making automatic priming possible.
“The new PAS dewatering pumps meet the five key criteria that Atlas Copco sets for the development of new machines: compactness, versatility, durability, efficiency and simple service,” says Wim Moors, vice president of pumps within Atlas Copco’s Portable Energy division.
“They are easy to transport to wherever you need them, tested in the toughest conditions, efficient in fuel consumption and able to cover multiple applications with a focus on modular design.”
The wide range of sizes in the new PAS portfolio starts with the 6.4kW PAS3, a wet prime pump offering a maximum flow capacity of 120m³/hour, a discharge size of 3ins and a maximum head of 24.5m.
At the other end of the spectrum, the dry-prime PAS 8 operates at a head of up to 30m; offers a discharge size of 8ins, and handles solids of up to 76mm with a maximum flow of 630m³/hour.
