Abstract (en)
[origin: EP0922812A2] A conveyor system for a two-phase flow, such as water containing sand, gravel and the like, comprising at least one conveyor pipeline (1) with means (2) for generating a flow, characterized in that the internal surface of the conveyor line bears guide means (7) for influencing the flow. A pump (2) is accommodated in the conveyor pipeline, and the guide means (7) are situated immediately upstream of the inlet of the pump. In case the pump is a rotary pump, the guide means are designed to impart a preliminary rotation to the flow. <IMAGE>
