Abstract In order to get the enlarged factors accurately,the principle and design aim of the enlarged flow design were briefly introduced.The mathematical formula was derived according to the principle of the enlarged flow design.By the relationship of the empiric data,the equations for the two factors of both enlarged flow and enlarged specific speed were established.The equations were numerically calculated and the corresponding curves were plotted.The curves contain the specific speed from 23 to 90 and flow rate from 3 to 30 cubic meters per hour.The current hydraulic models of the pump agree well with the curves calculated.
