WQ22Kw 30hp High Flow Submersible Pump For Clog-Free Efficient Wastewater Construction Site Drainage

The WQ series sewage pump is a robust and efficient submersible pump designed for handling wastewater, sludge, and other liquids containing solid particles or fibrous materials. Constructed with heavy-duty, corrosion-resistant materials such as cast iron or stainless steel, it ensures durability in harsh environments, including municipal sewage systems, industrial facilities, and construction sites. The pump features a high-efficiency motor with advanced cooling technology, enabling continuous operation even under partial submersion. Its anti-clogging impeller design and large flow channels minimize blockages, making it ideal for transferring heavily contaminated liquids. The WQ series is also equipped with automatic start-stop functionality, overload protection, and waterproof seals for enhanced safety and reliability. With versatile installation options (portable or permanent) and a compact design, it delivers powerful performance, energy savings, and low maintenance, meeting the demands of both residential and commercial wastewater management applications.
