Zusammenfassung:	The disclosure relates to a feed pump for hydraulic media having an input and an output. A pressure-reducing element is connected to the output, at the output of the element the system pressure being present and the output being connected to a consumer, wherein the output is connected to the first input of a pump controller, the second input being connected to the output of the pressure-reducing element, and wherein the pump controller adjusts the feed pump toward maximum delivery if the system pressure is smaller than a minimum pressure or if the system pressure is smaller than the feed pressure, and wherein parallel to the pump controller a pressure limiter is switched such that at the first input thereof the feed pressure is present and at the control input the system pressure is present, wherein the pressure limiter opens if the feed pressure is greater than a desired value.
