Function
The hydraulic power pack converts electric energy into hydraulic drive power. The electric motor (1) drives a
gear pump (26). Oil is delivered from the tank (9) to the pressure supply port (14) via the suction tube (24).
Pressure is indicated at the pressure gauge (12). The pump delivers oil at a nearly constant volumetric flow
rate.
The maximum pressure value is set at the pressure-relief valve (6). Oil is returned to the tank (9) via tank
port T (5) and the return filter (25). A blue coupling socket (4) is provided for return flow from the pressure
accumulator. The fill-level can be viewed at the sight glass (7). Oil is returned from the discharge measuring
container via the respective connection (15).
