KREBS pumps, developed by global minerals process specialist FLSmidth, have contributed to the mining industry’s energy conservation efforts. With the patented wear ring technology, these pumps have enabled mines to achieve significant levels of efficiency.
Revolutionizing Efficiency: The Impact of KREBS Pumps on Energy Conservation in Mining Operations
According to Stephan Kruger, FLSmidth’s Vice President for Pumps, Cyclones, and Valves in Sub-Saharan Africa, the Middle East, and South Asia, the mines have experienced a significant impact on the bottom line, especially when multiplied by numerous pumps employed at a single mine site.
He added that two primary factors contribute to decreased efficiency in slurry pumps: suction side recirculation and mechanical grinding between the casing and the impeller. However, the wear ring is crucial in mitigating these issues by significantly reducing both factors. As a result, the pump’s power consumption decreases, and the overall lifespan of the pump extends.
Derek Lane, General Manager of Operations, explained, “Conventional products in the market only address one factor, often compromising efficiency. However, KREBS pumps solve this challenge through the adjustable wear ring, maintaining constant pump speed and minimizing energy consumption, even in the face of grinding and wear.”
The wear ring can be easily adjusted while the pump runs, without special tools or shutting down operations. This seamless adjustability enhances the overall continuity and efficiency of the mining operations.
Additionally, the materials used in building KREBS pumps contribute to their longevity and sustainability. The material selection is based on application requirements and minimizing wear. Metal pumps employ high-chrome alloys, hypereutectic alloys, hypoeutectic alloys, and stainless steels, while elastomer options include natural rubber, polyurethane, and synthetics like neoprene. This careful selection reduces scrap produced from equipment replacement, aligning with the mining sector’s sustainability goals.
By incorporating KREBS pumps into its operations, mines have experienced substantial efficiency gains and reduced energy consumption. FLSmidth’s commitment to supporting customers through training and technical expertise further ensures these pumps’ optimal performance and longevity.
