FLSmidth Slurry Pump KREBS® gravelMAX

Key Benefits Pumps large and abrasive solids Adjustable while in operation Pulls a higher vacuum Reduces cost per ton Longer service life Optimized design for abrasive slurries with large solids Our innovative hydraulic design makes the gravelMAX the perfect solution for optimized passing size, efficiency and wear life. Treat the cause of slurry pump inefficiency with our gravelMAX pump Many slurry pump applications in hard rock mining, coal, dredging and other industries require the ability to pump large solids. Traditionally, operations used open impellers or extremely oversized pumps to get the job done – at the cost of ineffective performance. Our gravelMAX presents the ideal solution to optimise passing size, efficiency and wear life. This is due to its wide diameter impellers and large cutwater clearances for increased passing size, and our patented millMAX suction-side sealing system that eliminates the grinding of large solids. Lower Total Cost of Ownership In most established gravelMAX installations, wear life of parts has been even – and in the majority, overall wear life has improved by 50% to 100% compared to conventional slurry pumps. Installations have also noted a reduction in power consumption, typically in the range of 10% to 20% or even greater, which can then be taken as a cost savings or used for additional pumping capacity with the same installed motor. Industries and applications Aggregates (sand plants, cyclone feed, tailings) Dredging Coal (heavy media cyclone feed) Froth Heavy-duty abrasive slurries Any application requiring large solids passing Product Features Patented, proprietary features eliminate common problems The gravelMAX pump has a unique patented design developed for severe abrasive slurries. It features a proprietary suction-side sealing system and patented online wear clearance adjustment, which minimises the cost-per-ton pumped, compared to conventional hard metal and rubber lined slurry pumps. The gravelMAX not only eliminates inefficient recirculation but also the grinding of slurry. Our gravelMAX pumps are part of the ONLY pump line in the market that can eliminate both problems effectively. Additional features include: Adjustable wear ring Allows pumping of higher percent solids and higher-density slurries Reduces suction-side recirculation Maintains hydraulic performance millMAX™ power frame Heavy-duty cast pedestal External bearing assembly adjustment Wide bearing centres Heavy-duty shaft and bearings Reverse-taper roller bearings Increase the effective load span to improve B-10 life Pumping action of taper rollers discharges grease to the outside, preventing ingress of slurry and eliminating possibility of failure due to over-greasing
