Selecting a suitable sewage pump is crucial for sewage treatment projects. Start with water quality and solids content, then flow, head and installation environment. YINGZHI sewage submersible pumps handle municipal sewage discharge and building wastewater with an anti-clog hydraulic design; chopper (cutting) pumps macerate solids and fibrous matter before discharge; slurry pumps move abrasive, solids-laden water in river dredging and municipal sludge. All three run at 0-3400 r/min with permanent magnet variable frequency control and corrosion-resistant wetted parts. Contact us with your duty point for a model recommendation and quotation.
