A range of fully automatic dry self-priming centrifugal open-frame pumps aims to lower operating costs and increase productivity in the pump industry. The fit-for-purpose pump systems are designed to augment businesses while also being environment-friendly. 

Suitable for transporting or raising water with abrasive solids in suspension, Atlas Copco’s PAS diesel pump range comprises four high flow and five medium flow models, delivering a maximum flow capacity of 2100 m3/h, with a maximum head of 75 m and an outlet size of 100 mm to 300 mm.

The pump systems are specifically designed and engineered to deliver reliable operation in stringent conditions, where startup could be a challenge. The pumps’ dry prime capabilities aim to allow users to start pumping immediately. The system is equipped with a high-capacity diaphragm pump for automatic priming. The SuperDuo separator aims to make automatic priming possible by separating the air in the pump from the liquid, which is then sucked by the vacuum pump.

The pumps are designed to work with clean or dirty water that may include waste and fibrous materials. The inclusion of a centrifugal pump with a semi-open impeller and an abrasion-resistant pump casting allows for the pumping of liquids with solids of up to 100 mm in suspension, while reducing the risk of clogging.

The PAS range, which is also available in a canopy version, has been tested and verified and is suitable for a range of applications found in the construction, mining and municipal sectors, including general dewatering, wellpoint, floodwater clean-up, stream diversions, sewage bypass and reservoir, pond and canal drainage.

Additional features include:

• A high-efficiency hydraulic end, aimed at reducing fuel consumption.
• A modular design, allowing for multiple applications.
• Compact dimensions and light-weight design to facilitate manouverability.

Regular services by trained technicians using original-equipment manufacturer parts, aimed at extending the pump system’s life cycle and reducing maintenance and operational costs.

A hinged cover provides fast and easy access to components, promising a three-minute clean-up and restart.

A number of service packs are offered, including preventive maintenance kits, wear part kits, seal kits and gasket or O-ring kits.

Atlas Copco’s lubricants are especially engineered to match pump maintenance specifications and are aimed at providing optimal pump protection.                            

Atlas Copco also supplies a range of variable displacement wet self-priming centrifugal pumps available in open-frame and canopy versions. Encompassing eleven models, this range features outlet sizes of 40 mm to 300 mm, with a maximum head of 58 m and a maximum flow of 1 400 m3/h.
