Multi-stage Pumps QDX-C

Water supply from primary water supply tanks or reservoirs.5″ wells or Roman wells, basins and watercourses.Sprinkler irrigation systems.Pressure boosting with pumps inserted directly inside tankor well, to avoid suction problems and noise.Fountains.Close-coupled multi-stage submersible pump with electricmotor cooled by pumped liquid. The technopolymerimpellers and diffusers ensure superior performances andmaximum operational efficiency.The single phase version has an internal capacitor andbuilt-in thermal protection. For this reason, the pump doesnot require connection to a control panel for starting.
