This research developed ultra-pressure pump main body by using ductile cast iron FCD500,conducted quantitative analysis on following phenomenon of flow or solidification processing in castprocessing for improvement of cast device, after extracting model from cast concluded as follows bybrinel hardness test. after selecting the ideal condition of cast and it applied to cast of real productshape, discovered the ideal filling processing under the condition that temperature of molten metal wasbetween 1300℃ and 1280℃. and after finishing filling, solidification was commenced rapidly whenpercentage of solidification completion was between 40%~50%, at that moment, the termperature wasmeasured 1100℃. moreover under the condition of temperature below 900℃, keeping temperature on thecenter of parts for a certain period of time brings stability of stabilization of heat in parts andorganizational stabilization of ductile cast iron. As the results of the casting method design, it was thatthe ductile cast parts of pump main body was obtained as the maximum HB of 220 was recorded andgood test results were achieved
