<p>The method involves delivering a fluid by a pump (2), which has a pump drive and a bypass-line (7) having a bypass-valve (10). The bypass-line is provided for recirculation of fluid in an inlet side reservoir (6). The pump is controlled by the bypass-valve for reducing a flow volume during accelerating the pump drive to a specified speed objective, such that the flow volume lies between a cavitation flow volume and the increased cavitation flow volume at a specified maximal flow volume deviation by a delivery head. An independent claim is included for a pump arrangement.</p> |
