The diagram shows the implemented 2K system of a painting plant. Two standard UCP dosing
pumps are integrated in this system. The controls of the UCP continuously transmit the two A and
B component volume flow rates (actual values) to the higher-level PLC control of the painting
plant. PID controllers apply dosing pressure to keep the volume flow rates of the two components
within the specified nominal values. This constantly compensates changes in the viscosity of the
two components. A static mixer is used to mix the two components. The dosing system operates
in a pressure range of 10 to 60 bar and a paint mixture volume flow rate of up to 8 l/min.
