Atlas Copco is expanding its range of Weda electric submersible pumps in response to increased requirements on dewatering pump wear resistance and autonomous operation in mining and construction.
The four new models – Weda D80SH, Weda D81, Weda D91 and Weda D95SH – are rated 20-20-26-37 kW (50Hz, 60Hz: 31-31-40-58 HP) and can reliably pump solids-laden water with a specific gravity up to 1.1 and handle stones up to 12 mm (0.47 inch).
The new pumps also incorporate Atlas Copco’s Wear Deflector Technology, which was first introduced on the Weda D70 pump in 2021. The patented technology is the result of paradigm-shifting design and manufacturing methods that were unattainable until recently. State-of-the-art Computational Fluid Dynamics software is used to predict performance and eliminate potential hot spots for premature wear before a pump even enters the prototype stage. New 3D printing techniques are used for fast prototyping and enabling the casting of geometries that were impossible historically. For end-users, the result is a highly reliable dewatering pump that is easy to deploy, will run for more extended periods of time with minimal intervention, and can be readjusted to as-new performance to extend service life.
“Dewatering is a demanding and safety-critical operation, but there has been a lack of investment in developing better pumping solutions fit for the challenges of the 21st century,” said Bart Duijvelaar, Product Marketing Manager – Submersible pumps at Atlas Copco’s Power and Flow division. “Atlas Copco is the only company to have redesigned its dewatering pumps in the last decade using modern computational modelling and advanced manufacturing techniques. The result is the Weda range of pumps, which offer improved reliability and durability, are easy to deploy and maintain, and will work for longer with minimal supervision.”
