Get pumping with Atlas Copco’s portable and efficient dewatering pump solutions

The pioneering range of open-frame PAS dry and VAR wet self-priming centrifugal pumps from Atlas Copco Power Technique delivers the perfect balance between performance, versatility, efficiency and portability. Over 140 years of industry experience combined with a sound understanding of customer’s needs from all around the world as well as the purchase of market-leading pump designer and manufacturer, Varisco, are key factors that led to the development of the Atlas Copco dewatering range. Power Technique Business Line Manager, David Stanford, notes that Atlas Copco’s strategy, as a global leader in sustainable productivity solutions, is perfectly aligned to the pump industry. “Our primary focus is on providing efficient products which are better not only for our customers but also for the environment. To this end we develop products that are smaller and lighter with features that deliver the easy use, movement and maintenance trio. Furthermore, we place emphasis on versatility to ensure that we can provide the best solution appropriate for every industry that requires a pump solution from construction, general dewatering, wellpoint, sewage by-pass and reservoir, pond and canal drainage applications to emergency use, such as flood clean up.” Committed to reducing the customer’s operating costs for lowest possible total cost of ownership, Atlas Copco focusses its dewatering pump range on five key areas - compact, versatile, durable, efficient and simple service. Compact dimensions coupled with light weight makes the pumps easy to move keeping downtime to a minimum. “Our pumps can be transported and installed with minimum hassle, ready to handle dewatering requirements quickly and efficiently,” adds Stanford. In terms of versatility, Stanford says the focus is on modular design ensuring that one pump is capable of covering multiple applications; the requirement of fewer pumps adds to the customer’s bottom line. From a reliability perspective, these pumps have been tested and verified under the most stringent conditions for reliable performance over a long life span. “Efficiency,” says Stanford, “is one of the most important of the five focus areas. Featuring a high efficiency hydraulic end, our pumps are designed to operate in virtually any environment while consuming very little fuel.” Service was also taken into account during the design of these pumps which are equipped with a hinged cover for fast easy, access to components. The robust PAS and VAR pump systems are specially designed and engineered to deliver reliable operation in stringent conditions where start-up can often be a challenge. The PAS range features a high-capacity diaphragm pump for automatic priming. In the PAS pump system, the air is separated from the liquid in the large SuperDuo separator and is sucked by the vacuum pump, making automatic priming possible. Thanks to the pump’s dry prime capabilities, the end-user can start pumping immediately with a simple flip of the switch. The VAR, with its immediate water fill-in mechanism which makes it ready to prime and start pumping, being no exception. The inclusion of a centrifugal pump with a semi-open impeller enables both systems to pump liquids with solids of up to 76 mm in suspension without the risk of clogging. The PAS centrifugal diesel open-frame pump range comprises ten models which include three high-flow models, and has a maximum flow capacity of 1130 m3/h, with a maximum head of 58.5 m and an outlet size of 100 – 300 mm. Eleven models make up the innovative VAR centrifugal wet prime range. With an outlet size of 40 – 300 mm and a maximum head of 58 m, the VAR range delivers a maximum flow of 1400 m3/h. Atlas Copco Power Technique supports its comprehensive range of electrical, diesel and petrol dewatering pumps with excellent after-sales service further boosted by a countrywide dealer network.
