Submersible Sewage and Drainage Pumps patenteD Cable length 10 m, pump single-phase with plug Handle in polypropylene, with frame in stainless steel. easy inspection of the capacitor area. easy adjustment of the float switch: to allow the adjustement of start/stop pump levels. Ring against accidental extraction of the cable. the double shaft seal with oil chamber separates the motor from the water and provides further protection against accidental operation when dry. Relief valve: the pump is fitted to a relief valve for air release around the impeller granting a proper pump priming also...
