Abstract：Through improved design for IC slurry pumps,a design method with the dual "S" impeller was presented.By analyzing the passing mode of sundries in the slurry pumps with the dual "S" impeller,it was found that the long fibre effuses along the rear of blade,and passes easily in the "S" blade by long and short blade.The effects of geometry parameters of the impeller and volute for passing perfor-mance and efficiency were analyzed and the hydraulic design method was introduced.The test result shows that the dual "S" impeller of slurry pump reduces effectively foul sundries at the inlet and resolves the problem that the flow channel is easily jammed.In addition,the capability and efficiency of the pump are better than others used in the industry.Compared with other pumps,the actual head is increased by 0.6~1.1 m,NPSH is decrease by 0.2~0.5 m,the electrical power is reduced by 0.42~1.03 kW,and the efficiency is increased by 3%~6%.
