Abstract: Specified is a method for regulating the pressure of a fluid, moved through a pipe system with at least one consumer by a pressure generator, driven with an electric motor. In order to ensure a sufficient supply for all consumers on a continuous basis, the motor speed for adjusting the pressure in the pipe system is regulated by way of a controller. At least one control curve reflecting the fluid pressure in the pipe system in dependence on the amount of the fluid flowing through or the flow speed of the fluid is impressed into the controller. The control curve extends with a uniform curvature between a predetermined pressure minimum and a predetermined pressure maximum, such that in the direction of increasing pressure, it is located above a straight line connecting the points of minimum pressure and maximum pressure and is at the greatest distance from this straight line in the center region between the two points.
