Antofagasta Minerals’ Minera Los Pelambres, located in Chile, wanted to increase their reclaim water pumping capacity without changing its pipeline. After making a complete engineering analysis of Tranque El Mauro pumping system, Neptuno Pumps custom engineered ten high-head vertical turbine pumps that would operate at their best efficiency point. This allowed a 22% increase in pumping capacity and a 33% reduction in equipment, while saving more than US$ 1M in energy costs per year.
