ZW and self-priming sewage pump is the study of domestic and foreign similar technology is developed on the basis of a new structure of the product.

The self-priming pump set and non-clogged sewage into an organic whole, the axial back mixing type, and through the unique design of the pump body, impeller flow channel can be like general self-priming centrifugal pump, do not need to install the bottom valve and irrigation water, and can suck up row containing large particles and liquid long fiber impurities can be widely used in municipal drainage project, studied the breeding, light industry, papermaking, textile, food, chemical, electric power, chemical media such as fiber, paste and mixed suspension is the most ideal impurity pump.

Compared with domestic similar product, the pump has the advantages of simple structure, strong, good self-priming performance, high sewage capability, high efficiency and energy saving, convenient usage and maintenance for points, it belongs to the first creation in the country at sewage pump series products. The technical performance indicators in the domestic lead, reached the international advanced level, has wide application market and development prospects
