PROBLEM TO BE SOLVED: To reduce the height in an axial direction of a specified plunger, in a radial plunger pump. SOLUTION: A pump housing 13 supports a driving shaft 11 driven by a driving machine (electric motor M), and has a plurality of cylinders 15 which are arranged to an outer periphery of the drive shaft 11, equally spaced in a circumferential direction, and are radially extended. A plunger 17 reciprocating along with the rotation of the driving shaft 11 is assembled to each of cylinders 15. An intake hole 17a and an intake valve 39, and a discharge hole 15a and a discharge valve 31 are disposed to correspond to the plunger 17, so that fluid flows from an intake port 13c of the pump housing 13 into the intake hole 17a, and flows out from the discharge hole 15a into a discharge port 13d of the pump housing 13 through a discharge chamber R2. On a drive machine side from a plane including a center of axis of each plunger 17, an accumulator mounting hole 13e is formed in the pump housing 13 to be offset with respect to the center of axis of a specified plunger 17 and communicates with the discharge chamber R2.
