Zusammenfassung:	An agricultural sprayer includes a centrifugal pump (18) used for transferring fluid from a nurse tank (14) to fill a sprayer tank (12). It is sometimes required that the centrifugal pump (18) be primed in order to perform the transfer of fluid and this priming is done by creating a vacuum in a priming line (44) that is connected to a suction line (20) extending between an inlet of the pump (18) and to a discharge line (24) of the nurse tank (14), with the vacuum being caused by routing a flow of compressed air (36) through a venturi (40) having its throat (46) coupled to the priming line (44).
