ZW Non-Clog Sewage Pump

I. Product Overview

The ZW series self-priming non-clogging sewage pump is a new type of pump developed by our company. It integrates self-priming and sewage-handling capabilities by combining the structural and performance features of the ZX self-priming pump and the QW submersible sewage pump, while incorporating the advantages of similar international products. Like standard clean-water pumps, it requires no foot valve or manual priming. It is capable of handling sewage, sediments, mining waste, fecal matter, construction wastewater, and viscous liquids containing large solid particles (up to 60% of the discharge outlet diameter) and fibers (up to 1.5 times the impeller diameter). This pump significantly reduces manual labor intensity, offers ease of installation and use, requires minimal maintenance, and boasts performance that meets advanced international standards, promising broad market application and development potential.

Our products are designed and optimized using computer-aided technology. Backed by strong technical expertise, extensive manufacturing experience, and comprehensive testing facilities, we ensure consistent and reliable product quality.

II. Scope of Application

Suitable for industries such as chemicals, petroleum, pharmaceuticals, mining, papermaking, fiber and pulp processing, textiles, food processing, and power generation, as well as municipal sewage projects, public facility drainage, and aquaculture (river and pond farming).

III. Product Advantages

1. Strong sewage-handling capability: A special anti-clogging impeller design ensures high efficiency and clog-free operation.
