The present invention provides a technology for downsizing fluid pressure equipment including a fluid pressure pump and a radiator. The hydraulic pump unit 3 includes: a hydraulic pump 4; a motor 5 which drives the hydraulic pump 4; a cooling fan 7 which is connected to an output shaft 5a of the motor 5 and generates a flow of cooling air 6 to cool the motor 5; and a radiator 8 which receives heat from the hydraulic oil. The motor 5 and the radiator 8 are overlapped with the cooling fan 7, when viewed from the axial direction of the output shaft 5a of the motor 5.
