The present invention relates to a pulsation reduction device for a hydraulic piston pump comprising: a block housing of which one end part is connected with a first hydraulic circuit and the other end part is connected with a second hydraulic circuit; a damper embedded in the block housing and buffering pressure due to a working fluid introduced to the first hydraulic circuit and assisting pressure rise of the second hydraulic circuit and allowing shape deformation; and a viscosity reduction unit embedded in the block housing and disposed between the first hydraulic circuit and the damper and the second hydraulic circuit and the damper and reducing viscosity of the working fluid introduced from the first and the second hydraulic circuit. Therefore, the present invention reduces pulsation of pressure and relieves an impact and stably raise pressure with a relatively simple configuration. |
