Pumping grinding circuit slurries is one of the most demanding applications in mineral processing due to the high concentration of abrasive solids. KREBS® mill pumps from FLS are built to handle the job efficiently and reliably, maximising wear life and reducing cost per tonne pumped.
The first pumps to feature our proprietary adjustable wear ring technology, millMAX heavy-duty pumps set the standard for cost-effective slurry pumping. By eliminating particle degradation in the pump, they also help provide optimal feed to your mill.
The slurryMAX-XD horizontal pump features a heavy-duty impeller and thick, steel-reinforced elastomer linings to extend wear life, enabling it to handle the most aggressive applications, such as primary hydrocyclone feed.
The UMD ultimate mill discharge pump is the most advanced slurry pump for mill discharge pumping applications. Its optimised hydraulic pump design delivers the highest efficiency and even wear in the most abrasive mining applications. A wide flow casing option is available for wide operational process duty points.
FAQs for mill pumps
Our proprietary adjustable wear ring technology allows quick and easy control of suction-side clearance, increasing pump efficiency by 5-10% and helping maintain design performance over the life of the pump, without increasing pump speed. This results in lower power consumption and lower cost per tonne pumped.
Integrating superior hydraulic design with our patented suction-side sealing system, KREBS mill pumps reduce in-pump grinding and recirculation, maximising wear life and efficiency. It also protects against particle degradation that results in lost production in downstream ore recovery processes. The net result? Higher mill throughput without compromising the slurry or the pump.
With multiple elastomers, high-chrome alloys, and polyurethane combinations available, KREBS pump liners are customised the application to deliver even, predictable wear, enabling optimised maintenance scheduling to reduce downtime and inventory.
Our network of service and spare parts centres ensures timely access to spare/wear parts and fast offsite rebuilds. Expert site service engineers monitor pump performance, recommending upgrades or updates to operating practices to maintain BEP as process conditions develop over time. We also offer operation and maintenance training, including adjusting the wear ring.
