PROBLEM TO BE SOLVED: To provide a multistage pump capable of miniaturizing a pump and reducing the cost by reducing the number of components. SOLUTION: This multistage pump comprising a plurality of intermediate casings 2, 3, further comprises a discharge casing 4 having a baffle part 41 for preventing the abrasion of an inner face of the intermediate casing 3 of the final stage. An axial length of a cylindrical side part 31 of the intermediate casing 3 of a final stage is shorter than an axial length of the cylindrical side part 31 of the intermediate casing 2 of a prior stage.
