The ZW self-priming pump is developed by our company's designers based on the structure and performance of the ZX self-priming centrifugal pump and QW submersible sewage pump, drawing on the advantages of similar products at home and abroad, and absorbing the usage requirements and opinions of users from various aspects. It integrates self-priming and sewage treatment. It can not only be used without a bottom valve or water injection like a general water self-priming pump, but also suck up 60% of the large particle solid diameter as the outlet diameter and 1.5 times the fiber length as the impeller diameter, including dirt, sediment, waste mineral impurities, feces treatment, and all engineering sewage and glial liquids. It completely reduces the labor intensity of workers, and is easy to use, move, and install, with minimal maintenance and stable performance

Characteristics of high flow self-priming pump products
1. Adopting a double blade impeller structure greatly improves the ability of pollutants to pass through
2. The mechanical seal adopts a new type of friction pair and operates in the oil chamber for a long time;
3. The overall structure is compact, the volume is small, the noise is low, and the energy-saving effect is significant. It is easy to maintain and convenient for users to replace;
4. The automatic control cabinet can automatically control the pump's over movement and stop according to the required liquefaction changes, without the need for dedicated personnel to supervise, making it extremely convenient to use;
5. Installation methods can be provided according to user needs, which greatly facilitates installation and maintenance. People do not need to enter the sewage pit for this purpose;
6. Can be used within the design scope while ensuring that the motor does not overload;
7. If the pump is equipped with an outdoor motor, there is no need to build a pump room, and it can be directly installed and used outdoors to save costs;
Application of Strong Self priming Pump Products
High flow self-priming pumps are suitable for the discharge of severely polluted wastewater in factories and commercial areas, sewage discharge stations in main residential areas, water distribution systems in urban sewage treatment plants, drainage stations in civil air defense systems, water supply equipment in water plants, sewage discharge in hospitals and hotels, municipal engineering construction sites, mining auxiliary machinery, rural biogas digesters, farmland irrigation and other industries. They can also be used to transport granular sewage and pollutants, as well as clean water and weakly corrosive media.
