WARMAN Centrifugal Slurry PumpsExcellentMineralsSolutionsWRT Wear Reduction TechnologyThe new Warman WRT is a superior upgrade for your existingWarman AH pump designed to enhance efficiency and improvewear performanceWarman WRT advanced technology Increased wear life – the impellerthroatbush combination will increase wearlife between 30% and 50% Power savings – lower pump powerconsumption Cost reduction – higher pump efficiencysustained over a longer pumping operationtime Retrofit – new design parts retrofit to yourcurrent Warman pump Lower NPSH requirements – results inenhanced hydraulic performance andextended wear life Material combinations – rubber or metalpart combinations availableNew 4 vane impeller and matchingthroatbush design improve wearperformance assisting our customers inreducing their total ownership cost

After extensive research and development Weir Mineralsoffers advanced technology to reduce total cost of ownershipYears of actual wear data on the popular Warman AH pump design has enabled our design engineers touse a novel integrated design approach, comparingthis “real world” data with our Computational FluidDynamics (CFD) simulation to obtain correlationbetween predicted and actual results for the standard5 vane slurry impellers.CFD Software SimulationsThis has resulted in the introduction of the new WRT impeller and throatbush design. The new impellerdesign incorporates a unique vanelet on the backshroud which streamlines the flow through theimpeller. This new combination provides significantimproved wear life, with rigorous field testingshowing increases in wear life of up to 50% on theprevious design. This improvement also gives higherefficiency and therefore lower absorbed power andimprovements in the NPSH performance.8/6 AH NPSH test comparison- standard vs WRT impellerF6147@1000rpmNPSH (m)F6145WRT1@1000rpmFlow (l/s)5 vane designImpeller performance test data6080%70%WARMAN AH-WRT F6145WRT1 impellerperformance shownin orange5060%4050%30AH WRT design40%The green shaded area shows the efficiencyimprovement of the WARMAN AH-WRT impeller showing approximately 5% gaincompared to the existing five vane impeller2030%Noticeable hot spot reduction withnew WRT design20%10CFD Software used to predict hydraulic performance wasused to simulate wear hot spots and develop the newWRT designs.Standard F6147 5 vaneimpeller performanceshown in blue10%00%050100150200250300
