Get the job done efficiently with Atlas Copco’s smart surface dewatering solutions

Atlas Copco’s innovative surface dewatering pump ranges are defined by high performance, reliability, long lifecycle and ease of use, making them the preferred choice of countless industries that put them to work in multiple applications.

The rugged PAS dry self-priming and PAC H high head dewatering surface pump series feature a smart design, cutting-edge technology, quality components and advanced manufacturing to deliver best-in-class pumping solutions even in stringent environments.

The Atlas Copco Group has aligned itself with the UN sustainable goals and the Paris Agreement during product development and manufacturing practices. In line with the Group’s commitment in 2022, to follow science-based targeting with regards to emission reductions and global warming, efforts are focused on the development of more efficient, greener, carbon neutral products that offer sustainable solutions to customers and end-users.

“Our pumps are certainly no exception,” says Sarel Bekker, Business Development Manager at Atlas Copco Power Technique. “Our comprehensive range of super-efficient, robust, compact, versatile and easy-to-service pumps get the job done seamlessly while being respectful to the environment. We have a good understanding of pumps and their application and we listen to what our customers and end-users need.

The PAS range of fully automatic dry self-priming centrifugal pumps serve as a prime example of Atlas Copco’s commitment to developing smaller, lighter products. “Our PAS range deliver the five ‘easies’ i.e. easy to use, stack, pack, move  and maintain,” highlights Bekker. “Thanks to a modular design, one pump is capable of covering multiple requirements. The need for fewer pumps combined with fast easy manoeuvrability enhance uptime and productivity.”

Equipped with a high efficiency hydraulic end, the PAS pump range consumes very little fuel irrespective of the operating conditions. This market-leading fuel efficiency also means that these units are able to operate continuously for 24 hours. All these value adding features help to reduce Operational Expenditure (OPEX) for ultimate lowest total cost of ownership.

The PAS range delivers a maximum flow capacity of 2100 m3/h, with a maximum head of 75 m and an outlet size of 100 – 300 mm. These fit-for-purpose diesel pump systems are equipped with several features that render them particularly well suited for mining applications. With the ability of working with clean or dirty water and handling trash and fibrous materials with ease, these pumps can pump, raise and transport liquids with solids of up to 100 mm in suspension over long distances without the risk of clogging. This exceptional solids-handling capability is due to the inclusion of a centrifugal pump with a semi-open impeller and an abrasion-resistant pump casting.

The robust PAS pumps’ dry prime capabilities enable the user to start pumping immediately with a simple flip of the switch, ensuring reliable operation in stringent conditions where start-up can often present a challenge. The system’s high-capacity diaphragm pump allows for convenient and time-saving automatic priming.

Atlas Copco’s PAC H pumps offer a turnkey solution for high-pressure applications. Part of Atlas Copco’s renowned Head series, this high head centrifugal pump combines performance and efficiency in one smart package. The unit is capable of handling liquids containing solids of up to 89 mm and features a maximum head size of up to 150 m and a maximum flow of up to 1200 m3/h. The PAC H series is well suited to industrial applications such as water transfer, benefitting industries such as oil & gas, quarrying, surface mining and construction as well as the municipal sector.

The new PAS 100 and PAS 150 HardHat® models feature Atlas Copco’s unique HardHat® Technology which ensures a high level of robustness and durability in any condition. Made of medium-density polyethylene instead of metal, the canopy effectively protects the working operation underneath from the elements. These clean, green machines are fully EU emission compliant and feature a 120% fully leak-free structure. PAS HardHat® pumps incorporate digital technology in the form of QR codes that provide essential parts and spares information with one quick easy scan.

The speed in which service and maintenance work can be carried out is fundamental to high equipment availability and subsequent prolonged uptime. So Atlas Copco ingeniously centred the design of the PAS and PAC H pump series on serviceability. “Regularly service carried out by trained Atlas Copco technicians using OEM parts, will contribute to reduced maintenance costs, improved pump reliability, prolonged life cycle, and maximised operational efficiency and productivity,” notes Bekker. Wear components can be serviced and replaced without dismantling the pump owing to Atlas Copco’s semi-cartridge seal design, hinge kit, bolted wear plate and link belts. This both simplifies and speeds up pump maintenance. The standard semi-cartridge seal, which is normally an optional extra on other pumps, makes the lip seal and impeller easily accessible. The innovative hinge kit includes a ‘swing door’ that allows quick and easy access to the pump’s internal workings. By using link belts to enable changeovers without having to dismantle the entire wet end of the unit, reduces MTTR (mean time to repair) by up to 30%. The impeller is easily removed with a single bolt and the hinged cover provides fast easy, access to components, enabling an industry-leading three-minute clean up and restart.

Atlas Copco also offers service packs including Preventive Maintenance Kits, Wear Part Kits, Seal Kits and Gasket or O-Ring kits. “Our high performance long-lasting lubricants have been especially engineered to match pump maintenance specifications and provide optimal pump protection,” adds Bekker.

“The countless outstanding time and cost saving benefits presented by our PAS ranges make these pumps ideal for an extremely wide range of industries such as oil & gas, mining and quarrying, construction, civil works, industries, well point, municipalities as well as rental,” confirms Bekker. “Applications are even wider, ranging from dewatering, site drainage and sludge removal to jetting, flood control and even temporary firefighting protection, to name but a few,” he concludes.
