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 first reversal point and the second reversal point, the movement direction of the piston is reversed, wherein during an output period, the fluid medium is output by means of an output device, and during an interruption period, an output of the fluid medium by means of the output device is interrupted, wherein during the interruption period, the movement direction of the piston is reversed, wherein on reversal of the movement direction during the interruption period, the piston is situated at an intermediate position between the first reversal point and the second reversal point.
A double-action piston pump for delivering a fluid medium to an output device, 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 the piston pump has a control device for controlling a movement direction of the piston, wherein the control device is configured to reverse the movement direction of the piston on reaching the first reversal point and the second reversal point, wherein the piston pump has a measuring device for measuring a piston speed, wherein the control device is configured to reverse the movement direction of the piston if the measured piston speed is less than a specific speed value.
