Atlas Copco’s rugged PAS dry self-priming and PAC H high head dewatering surface pumps feature smart design, cutting-edge technology, quality components and advanced manufacturing to deliver best-in-class pumping solutions. The PAS range of fully automatic dry self-priming centrifugal open-frame pumps serves as a prime example of Atlas Copco’s commitment to developing smaller, lighter products that are easy to use, easy to move and easy to maintain. Also available in a canopy version, the PAS range comprises four high flow (HF) and five medium flow (MF) models delivering a maximum flow capacity of 2100 m3/h, with a maximum head of 75 m and an outlet size of 100 to 300 mm.
These fit-for-purpose diesel pump systems are equipped with several features which render them ideal 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 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 pump system’s high-capacity diaphragm pump makes automatic priming possible; the air in the pump is separated from the liquid by the large SuperDuo separator which is then sucked by the vacuum pump.
The company’s PAC H high-head pumps combine performance and efficiency in one smart package. Featuring a maximum head size of 150 m, a maximum flow of up to 1200 m3/h and a solids-handling capability of up to 89 mm, the PAC H series is particularly suited to industrial applications such as water transfer and will benefit industries such as oil & gas, quarrying, surface mining and construction as well as the municipal sector.
Atlas Copco has centred the design of its PAS and PAC H pump series on simplified serviceability. If performed regularly by trained technicians using OEM parts, service will improve pump reliability, prolong life cycle, maximise uptime and reduce maintenance costs, all factors that are fundamental to operational efficiency, ultimately adding to the end-user’s bottom line.
The hinge kit available on the PAS range, simplifies and speeds up pump maintenance. The pump is fitted with a hinged cover which provides quick and easy access to components, enabling a three-minute clean-up and restart. The service and maintenance process on the PAC H pumps is facilitated as wear components can be serviced or replaced without the need to dismantle the pump.
