To provide a pump device capable of effectively reducing a pulse pressure.SOLUTION: A pump device includes: a motor; a rotary shaft rotated by the motor; a drive part arranged on an outer periphery of the rotary shaft, and including a cam eccentric to a rotation axis of the rotary shaft; and a plurality of plunger pumps actuating in the direction orthogonal to the rotation axis, on the outer periphery of the drive part. When N is an integer of 2 or greater, the plurality of plunger pumps are arranged in N-pieces of rows deviated from one another in the direction where the rotation axis extends. The total number of the plunger pumps is an odd number.SELECTED DRAWING: Figure 11

    【課題】 脈圧を効果的に低減できるポンプ装置を提供する。【解決手段】 ポンプ装置は、モータと、モータによって回転される回転軸と、回転軸の外周に配置され、回転軸の回転軸線に対して偏心したカムを含む駆動部と、駆動部の外周で、回転軸線に対して直交する方向に作動する複数のプランジャポンプとを備える。Nを2以上の整数としたとき、複数のプランジャポンプが、回転軸線が延びる方向に互いにずれるN個の列に配置される。プランジャポンプの総数が奇数である。【選択図】 図11
