A hydraulic aggregate, particularly for supplying conveyor and lifting devices with pressurized fluid, has a tank (1) on the end side relative to a main axis of the device and functional components mounted on it. The functional components are a hydraulic pump (5) and a coupling body (3) having a valve device and a line arrangement for drawing in and returning hydraulic fluid to and from the tank (1). Configured as a reversing aggregate, the inlet end (19) of the suction line (15) of the line arrangement is disposed at a location within the tank (1) where the bottom of the fluid present in the tank (1) is located when the aggregate is operated with the main axis vertical and when the aggregate is operated with the main axis tilted relative to the vertical, preferably perpendicular to the vertical.
