PROBLEM TO BE SOLVED: To provide a hydraulic machine unit that can greatly contribute to energy saving and resource saving by facilitating the installation work of a hydraulic machine, and optimizing the characteristic of the hydraulic machine. SOLUTION: This hydraulic machine unit is integrally provided with a pump 10 driven by a motor 12; a flow control valve 30 for controlling the flow of liquid flowing inside the pump 10; a valve operating mechanism 32 for operating the flow control valve 30; and an inverter 20 for controlling the rotating speed of the motor 12. The characteristic of the pump 10 is freely controlled by the flow control valve 30 and the inverter 20.
