The impeller is enclosed within a single impeller bowl, which is connected by a pumping chamber. When the impeller rotates, the liquid inside the pump creates a violent axial vortex, resulting in a vacuum at the inlet and pressure at the outlet. This design allows foreign substances to be discharged from the pumping chamber, ensuring that the flow channel is fully cleared. As a result, the discharge capacity of this pump is unmatched when compared to other self-priming pumps.

The ZW self-priming non-clogging sewage pump combines the functions of self-priming and non-clogging sewage disposal. It does not require a bottom valve or water for priming like conventional clean water self-priming pumps. This pump is capable of handling wastewater containing solid particles, long fibers, sludge, waste mine impurities, fecal matter, and all types of construction wastewater. It significantly reduces labor intensity, while offering easy installation, movement, and minimal maintenance, all while providing stable performance.

Application Range
Ambient temperature T≤45℃, medium temperature T≤60℃
For cast iron pumps, the medium pH value is 6-9; for stainless steel pumps, the pH value is 1-14
The maximum particle size that can pass through is 60% of the pump’s diameter, and the fiber length can be up to 5 times the pump’s diameter
The total weight of impurities in the medium should not exceed 15% of the total weight of the medium, and the medium's specific gravity should not exceed 1240 kg/m³

Application
Widely used in urban sewage discharge systems, light industry, papermaking, textiles, food, chemicals, power generation, petroleum, mining, agriculture, and more. It is an ideal choice for handling solid particles, fibers, pastes, and mixed or suspended media in domestic trash pumping applications.
