Abstract: A device for intermittently applying a flowable substance to a substrate includes an applicator nozzle for applying the flowable substance to the substrate, a tank for holding the flowable substance, a pump for delivering the substance, and a drive means, wherein the pump is actively connected to the tank and driven by drive means, and further including an actuator actively connected to the pump and transferred into two positions, in a first position the actuator conducts the substance to the applicator nozzle, and in a second position blocks the feed to the applicator nozzle, and further including a control device for activating the actuator and for regulating the speed of the drive means of the pump. A method for applying the substance using the device is also provided.

Abstract: A piston pump and a method for determining a volume Veff of a liquid medium delivered to a consumer by a double acting, pneumatically driven piston pump, wherein the piston pump is subject to leakage when a constant pressure is acting on a drive of the piston pump and at least one double stroke of a piston pump from one dead center position thereof to the other dead center position thereof and back to the first dead center position is carried out includes: a. without the piston pump being able to deliver the medium to the consumer, a leakage time tL auf for one stroke of the piston pump from the bottom dead center position thereof to the top dead center position thereof is measured, b. without the piston pump being able to deliver the medium to the consumer, a leakage time tL ab for one stroke of the piston pump from the top dead center position thereof to the bottom dead center position thereof is measured, c. a quotient of a volume of the medium Vauf theoretically delivered by the piston pump without leakage and of the leakage time tL auf is determined for the stroke of the piston pump from the bottom dead center position to the top dead center position, d. a quotient of a volume Vab theoretically delivered by the piston pump without leakage and of the leakage time tL ab is determined for the stroke of the piston pump from the top dead center position to the bottom dead center position, e. the time tauf for the stroke of the piston pump from the bottom dead center position to the top dead center position and the time tab for the stroke of the piston pump from the top dead center position to the bottom dead center position is measured as the medium is delivered to the consumer, f. the effectively delivered volume Veff is multiplied by the number of double strokes in accordance with V eff = ( V auf - V auf t L auf × t auf ) + ( V ab - V ab t L ab × t ab ) .

Abstract: 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 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.
