Featuring our proprietary wear ring technology, KREBS® heavy-duty pumps reduce power consumption and extend wear life when pumping abrasive slurries. These reliable workhorses are built for mineral processing applications and others that require durable and reliable performance in harsh conditions.
Our proprietary adjustable wear ring technology enables quick, easy, and safe control of suction-side clearance while the pump is operating. By maintaining the optimal gap and preventing the grinding of solids between the impeller and suction side, our wear ring technology increases pump efficiency by 5-10% in slurry applications. The result of this is lower power consumption and a lower cost per tonne pumped.
By closing the gap and preventing recirculation within your pump using the adjustable wear ring, while also avoiding the grinding of solids between the impeller and suction side, KREBS pumps maintain design performance over their entire lifetime without the need to increase RPM. As a result, wear life is extended by 50-100% compared to traditional pumps.
With multiple elastomers, high-chrome alloys, and polyurethane combinations available, KREBS pump liners are customized for each application to deliver even, predictable wear. This enables optimized maintenance scheduling, reducing both downtime and inventory.
When pumping large solids, the gravelMAX pump is your answer. A large impeller-suction side clearance prevents in-pump grinding when entering the pump, while a wide-diameter impeller and increased cutwater clearance allow solids to exit the pump.
The first pumps to feature our suction-side sealing system, the millMAX heavy-duty pump sets the standard for cost-effective slurry pumping.
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, including primary cyclone feed and tailings.
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.
The UMD-R is a fully rubber-lined, split-case version of the UMD mill discharge slurry pump, particularly suited for wide flow ranges and corrosive duties.
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.
