Claim 10:
11. The dilute phase powder pump according to claim 10,
wherein the device for functional testing comprises an evaluation device for evaluating the static and/or dynamic pressure value detected by the at least one pressure sensor and/or for evaluating a chronological progression of the static and/or dynamic pressure detected by the at least one pressure sensor, wherein the evaluation device is designed to detect at least one of the following situations on the basis of the pressure value detected by the at least one pressure sensor and/or the progression of pressure detected by the at least one pressure sensor as well as on the basis of the volume of conveying air or supplementary air respectively supplied to the conveying air inlet and/or the supplementary air inlet per unit of time:
wear and/or degree of wear of the collecting nozzle;
an at least partial blockage at the powder outlet of the dilute phase powder pump;
an at least partial blockage at the powder inlet of the dilute phase powder pump; and
a deficiency of powder, particularly coating powder, in the powder reservoir fluidly connected to the powder inlet of the dilute phase powder pump.
