<p>The plant has a dosing pump (2) provided for dosing a coating medium e.g. paint, with a certain discharge quantity, and an adaptation unit (9) connected with a pressure sensor. A color pressure controller is arranged upstream of the dosing pump and adjusts coating medium pressure at an inlet of the dosing pump. A control unit (7) controls the color pressure controller and adjusts the pressure difference at the dosing pump, as a control-or regulating parameter, to a constant preset value independent of discharge quantity of the dosing pump. An independent claim is also included for an operating procedure for a coating plant for painting motor vehicle-body parts.</p> |
