High-capacity municipal wastewater influent lift stations and storm drainage systems run their equipment. ## **What to Consider When Choosing a Manufacturer** Application requirements and regional support narrow down the list fast. Solids handling matters most for sewage with rags and debris, where Gorman-Rupp’s shimless adjustment, Xylem’s chopper systems, and DEFU’s 76mm solids-passing designs prevent clogging. For corrosive effluents, DfEFU’s stainless steel JT/JU Series and Sulzer’s hard metal castings handle acidic or chemically aggressive wastewater. Large-scale municipal operations in Asia, Africa, and the Middle East often turn to Kirloskar and WPIL for mega-capacity configurations. Parts interchangeability cuts long-term costs. DEFU’s pumps interchange with Cornell and Gorman-Rupp, which simplifies spare parts sourcing for existing installations.
