Abstract: A pump technology that provides for more effective and efficient transfer of liquids, such as petroleum products and components, to and through pipelines. Such a technology can comprise a type of external gear pump that creates higher flow, resulting in higher pressures in the pipeline, to move the liquids, while providing for longer pump life, simpler and less maintenance, and fewer undesired conditions, with a smaller footprint, in a cost-effective system. Further, one or more portions of the pump can be configured to be easily replaceable to provide for maintenance in place, and provide for longer pump life. Additionally, one or more portions of the pump can be constructed with or coated with abrasive resistant material that extends the life of the external gear pump. Such material can also reduce the friction between surfaces and improve the life of the external gear pump under poor feeding conditions.
