Method for operating double-acting piston pump of application system

A method for operating a double-action piston pump of an application system for applying a fluid medium to a substrate, wherein the piston pump has a piston which is movable between a first reversal point and a second reversal point for delivering the fluid medium, wherein on reaching the respective reversal point, a movement direction of the piston is reversed, wherein the application system has an output device for intermittent output of the fluid medium delivered by means of the piston pump to the output device, wherein during an output period, the fluid medium is output by means of the output device and during an interruption period, an output of the fluid medium by means of the output device is interrupted, wherein during at least one interruption period, the movement direction of the piston is reversed, wherein on the reversal of movement direction during the at least one interruption period, the piston is situated at an intermediate position between the first reversal point and the second reversal point.
