A hydraulic drive with rapid stroke and load stroke, preferably used for a hydraulic press, including a first differential cylinder that includes a first and a second pressure chamber and a piston that separates the first from the second pressure chamber and having two pumps delivering in opposite direction. The hydraulic drive further includes a second differential cylinder that includes a first and a second pressure chamber and a piston that separates the first pressure chamber from the second pressure chamber, and a directional control valve that has a first and a second switching position. The pumps in the first switching position are respectively hydraulically connected via pressure chambers of the first differential cylinder that are different from each other and whereby the pumps in the second switching position are respectively connected via pressure chambers of the second differential cylinder that are different from each other.
