Claim 11:
12. The dilute phase powder pump according to claim 11,
wherein the device for functional testing comprises a storage device in which are stored target values of a static pressure in an area of the fluidic connection between the powder inlet of the dilute phase powder pump and the powder inlet of the drive nozzle for different powder hoses fluidly connected at the powder outlet of the dilute phase powder pump for defined values of the volume of conveying air or supplementary air supplied to the conveying air inlet and/or supplementary compressed air inlet per unit of time, and wherein the evaluation device is designed to detect the pressure of a powder hose actually connected fluidly at the powder outlet of the dilute phase powder pump, in particular its length and/or its flow resistance, 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 and in consideration of the target values stored in the storage device.
