1 PuMPs & Wet-End conversion Kits for Severe Duty SlurrymillMAX PuMPsThe millMAX Pump has a unique patented design developed exclusively for mill discharge duties and adapted for other severe abrasive slurries. The same wet end components can be offered as a conversion kit to existing PuMPs , without the need to disturb the foundation or existing bearing frame millMAX Pump features a patented on-line wear clearance adjustment, which minimizes the cost per ton pumped compared to conventional hard metal and rubber lined slurry PuMPs through: Increased wear life Even wear life of all wet end parts Less down time Lower power consumption Increased mill throughput More consistent cyclone separationmillMAX Solves This Kind of ProblemmillMAX after 1500 hours of wearCompetitor s suction liner and impeller - 550 hoursWide clearances at expelling vanes prevents large solids from being clearances at the wear ring prevents suction-side clearances at backliner ensures that shaft sealing system works of the Design Improved gland seal performance
2 Low-cost no risk wet end replacementmillMAX Hybrid Suction Sealing SystemThe patented on-line suction side wear clearance adjustment per-mits the initial clearances to be maintained throughout the life of the pump. This extends the life of the impeller and suction wear faces to near, or equal that of, the casing for a one time mainte-nance reduction of solids grinding between the impeller and suction side reduces power consumption and wear. The millMAX Hybrid Suction Sealing System maintains constant flow and pressure, with-out increasing speed or the danger of motor millMAX TECHNOLOGYWET END CONVERSIONS millMAX PuMPs 20x18-46 Ghana Quick-Release 20x18-43 Australia Gold 14 x 12 Chile Copper 16x14 Zambia Copper10 x 8 US Coal 6x4-21 S.
3 Africa High PressureKrebs millMAX PuMPs treat the cause of pump wear and loss of efficiency, whereas competitive PuMPs treat the symptoms through materials or predictive uneven wear most established millMAX installations, wear life of parts has been even and in the majority, overall wear life has generally improved by 50% to 100%. This increase in wear life is achieved together with a reduction in power, generally in the 10% to 20% or lower reduction in power can then be taken as a cost savings, or through additional pump-ing capacity with the same installed the millMAX Hybrid Suction Sealing System, the front clearance is adjusted while the pump is running, and takes only five minutes to perform.
4 This clearance is adjusted normally six to eight times throughout the life of the wet end millMAX design can be applied to an existing pump through a wet end conversion kit, including impeller, casing, backliner, and gland millMAX conversion kit is supplied with an adapter ring, seals, and all hardware to adapt to a variety of power frames. This achieves the same results as a complete pump on a maintenance 20x18-46 Australia GoldTECHNICALHigh Performance Centrifugal Dry Gland Seal Large expeller diameter gener-ates high suction level sealing capacity.
5 Zero leakage while Taper Roller Bearings Increases effective load span to improve life. Main bearing failure is due to over greasing. Pumping action of taper rollers discharges grease to the outside, preventing ingress of slurry or over greasing of bearing - designed for minimum slurry turbulence and even wear. Includes (14x12 and smaller) integral wear ring, carrier, and adjustment screws for on-line adjustment and elimination of suction side RING - adjustable wear ring assembly to permit closing of suction side impeller clearance during operation.
6 This reduces slurry recirculation and lowers pressure at the suction area, thereby maintaining flow and reducing - designed for high slurry efficiency and hydraulic performance. Machined surface at the eye for wear ring adjust-ment and high expelling - designed for close clearance at the back (14x12 and smaller), or SUCTION LINER with integral wear ring (16x14 and larger). Matching full impeller diameter and profile for close operating PARTS - designed hydraulically to wear evenly. Construct-ed of high chrome at 680/720 Brinell FRAME - heavy duty cast iron pedestal with external bearing assembly adjustment mechanism.
7 Drilled for overhead motor mounting - loose intake and discharge flanges drilled to suit vari-ous pipe ASSEMBLY - heavy duty shaft and indirect fitted taper roller bearings rated at 100,000 hrs B-10 life minimum. Bearing arrangement designed to prevent over greasing and ingress of PuMPs are Krebs millMAX design and include the following: millMAX Power Frame Heavy duty cast pedestal. External bearing assembly adjustment. Wide bearing centers. Heavy duty shaft and bearings.

9 Increased wear life. Reduced power Mechanical Seal Operates in extreme abrasive environment. Individual seal wear parts are easily replaced on-site without special tools. Ability to adjust for wear if required.
