      Backwash sewage lifting equipment

      HWT-FC sewage lifting equipment is a highly integrated sewage discharge system, which collects sewage and wastewater lower than the system pipe network through the water collecting tank and lifts it to the outdoor drainage pipe network by using the lifting pump. It consists of a water collecting tank, a temporary storage box for sundries, a sewage pump, an automatic level gauge and an electrical control device. At first, sundries are trapped in the slag temporary storage box, and the filtered sewage flows into the water collecting tank. When the liquid level in the water collecting tank reaches the starting liquid level, the sundries intercepted in the sundries temporary storage box are reversely discharged into the outdoor pipe network when the water pump starts. Applicable to: toilet sewage, rainwater, catering industry, entertainment industry, leisure service industry, construction engineering, commercial engineering, chemical plant, production and processing plant, pharmaceutical factory, hospital, municipal engineering and other underground sewage secondary lifting systems.
