A pipeline pump is a type of single-suction single-stage or multi-stage centrifugal pump. It has a vertical structure. Because its inlet and outlet are on the same straight line and have the same diameter, it resembles a section of pipe and can be installed at any position on the pipeline, hence it is called a pipeline pump. Structural features: It is a single-suction single-stage centrifugal pump with the same inlet and outlet on the same straight line, perpendicular to the center line of the shaft, and it is a vertical pump.
