A pump system includes a triple-gear pump which pressurizes a fluid using three gears; an outlet flow path which guides the fluid from a first pressure-increasing portion to an outlet; a first flow path which guides the fluid from the first pressure-increasing portion to a second pressure-increasing portion; a second flow path which guides the fluid from the second pressure-increasing portion to the outlet flow path; a third flow path connected to the first flow path and the second flow path; a first valve device provided in the first flow path; a second valve device provided in the second flow path, and a control device which controls the first valve device. When the first pressure-increasing portion and the second pressure-increasing portion are switched from a parallel state to a series state, the control device causes the first valve device to open after the second valve device is closed.
