Abstract
A paint circulating system is suitable for providing paint to applicators in a product finishing facility. The system includes a pump for pumping paint around the system and a back-pressure regulator (BPR), which substantially eliminates pressure fluctuations of paint in the system upstream of the BPR. A controller is provided for controlling the pump and the BPR to operate in one of a flow mode, wherein a required flow rate of paint around the system is maintained, and a pressure mode, wherein a pressure of paint between the pump and the BPR is maintained. The paint circulating method includes switching operation of the pump and the BPR between the flow mode and the pressure mode.
