The pumping set comprises an electric motor (10), the output shaft (12) of which is drivingly connected to a piston pump arrangement (14) for delivering hydraulic fluid. To prevent hydraulic fluid, which escapes at the piston pump arrangement (14) during operation, from passing into the interior (39) of the electric motor (10), a collecting region (30) is provided, which is connected to a storage chamber (36) in order to receive hydraulic fluid therein.
