A loop reactor axial pump system improves conversion of tangential to axial flow of a flowing slurry by attaching a straight impeller section to the inlet of an elbow section. A pump shaft extends rotatably from the elbow through guide vanes located in the impeller section, so that flow from an impeller mounted on the shaft passes through the guide vanes before entering the elbow. When the impeller section is detached, the guide vanes have "see through" access from both ends, thereby allowing the guide vanes to be longer and/or more curved than in the prior art. Guide vanes can be straight or curved, and can have inlet angles approximating the absolute flow angle of the fluid, and/or outlet angles approximating 0 degrees. Additional guide vanes can be included in the elbow. Additional straight pipe sections containing only guide vanes can be included between the impeller section and the elbow. |
