Pipeline pump is a novel pump developed for pipeline pressurization and transportation to solve the problem of low pipeline pressure. It has great advantages over the horizontal centrifugal pump currently used. The pipeline pump has the following characteristics:

1. The pipeline pump has compact structure, integrated machine and pump, and small volume. The vertical structure has the advantages of small installation area, stable operation, and installation without adjustment.

2. The inlet and outlet of the pump are designed as flanges with the same specification, and they are located at the same center line. They can be directly installed on the pipeline like valves, and the center is low, which is convenient for pipeline layout and installation.

3. The pump is coaxial with the motor, and the axial dimension is short, which makes the pump run more smoothly and has low noise.

4. The traditional shaft seal mode is canceled to avoid the leakage of the transmission medium, so it has the remarkable feature of no leakage.
