In a multistage pump with a pump casing divided into upper and lower halves, circumferential grooves centered on the pump shaft are arranged in parallel in each stage of the casing in correspondence to the number of stages. Then, one set of the parts forming the partition plate and the guide vane or the volute part are fitted, each partition plate and the casing are prevented from rotating, and further the part forming the partition plate and the guide vane or the volute part is fitted. Stopped top and bottom split multi-stage pump. 2. A request for utility model registration in which the dimensions of the grooves into which parts forming the partition plates and guide vanes or volute parts of each stage are fitted are the same as the dimensions of the grooves into which other parts such as the central partition plate balance piston chamber casing are fitted. The upper and lower split type multistage pump described in item 1.
