QDT Type Low-Speed Flow Inducer, widely used in water treatment processes for oxidation ditch flow, mixing in various biochemical pools, and also for river anti-freezing and landscape water circulation. The low-speed flow inducer consists of a submersible motor, a reduction unit, a propeller blade, and an installation system. It features a small matching power (1.5~7.5kW), low speed (36~135r/min), large propeller blade diameter (1000~2500mm), slow rotation, producing a large flow field, and a wide service range.
