ZX series self-priming pump is a self-priming centrifugal pump. The self-priming centrifugal pump has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, and it is only necessary to ensure that there is a quantitative liquid in the pump body before work. Therefore, the self-priming centrifugal pump simplifies the pipeline system and improves the working conditions.
