Self-priming centrifugal pumps have the advantages of compact structure, convenient operation, stable running, easy maintenance, high efficiency, long service life and strong self-priming capacity. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to keep a certain amount of priming liquid in the pump body. Therefore, the pipeline system is simplified and the working conditions are improved.
