A method and a control arrangement for driving at least one hydraulic consumer are disclosed. The control arrangement comprises a pump whose output is adjustable as a function of the load pressure of a consumer. The consumer is driven through a proportional directional valve forming a measuring orifice, a pressure compensator being associated with the directional valve, allowing the pressure drop across the measuring orifice to be maintained constant irrespective of the load pressure. According to the invention, a low load pressure is indicated to the pump when the pressure compensator is completely open, so that the pressure drop across the measuring orifice is reduced.
