Patent number: 11291963Abstract: A device and related method for producing a ready-to-use solution from a concentrate and a diluent includes an inlet for the diluent; an inlet for the concentrate; an outlet for the solution; a line extending from the inlet for the diluent via a confluence where diluent and concentrate meet, to the outlet; a mixing container arranged in the line between the confluence and the outlet and having a larger cross-section than parts of the line, which are arranged upstream and downstream of the mixing container; and a metering pump for the concentrate, which is connected on the suction side to the inlet for the concentrate and on the pressure side to the confluence and which operates in a pulsed manner. The metering pump works with a clock frequency, in which a plurality of pump surges are attributable to the dwell time of the liquid in the mixing container.Type: GrantFiled: January 17, 2017Date of Patent: April 5, 2022Assignee: WashTec Holding GmbHInventors: Ulrich Kölbl, Michael Schwärzer, Helmut Oswald, Franz Kiser, Stefan Mayer
