Atlas Copco expands range of PAS pumps

Atlas Copco has launched 18 new additions to its open frame diesel-driven centrifugal dewatering pump range.

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.

The new pumps provide a wide range of sizes, with discharge size ranging from 3” to 8” and the PAS open-frame system comprises a centrifugal pump, semi-open impeller, and a large separator.

The dry prime variants offer rapid priming time and higher capacities, and the wet prime pumps are a portable, cost-effective solution, best suited to applications with a consistent flow.

The PAS range benefits from mechanical shaft seals being set in an oil bath, which enables dry running capability without damage.

A high efficiency hydraulic end lowers fuel consumption, while a high capacity diaphragm pump supports automatic priming.

The semi-open impeller enables the pumps to handle solids of various sizes, without the risk of clogging.

Additionally, all components are easy to access, which allows for simple servicing and maintenance.

The 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/hr, a discharge size of 3” and a maximum head of 24.5m, capable of handling solids of up to 40mm.

The dry-prime PAS8 operates at a head of up to 30m, offers a discharge size of 8” and handles solids of up to 76mm with a maximum flow of 630m3/h.

With the combination of models now available, the range offers an efficient solution for any application and flow level between these two points.
