Single impeller electric pumps specifically designed to obtain high capacities related to medium-low pressure (and output). The pump-body and impeller design, characterized by large passages makes this pump suitable to both clean water and liquids charged with moderate impurities which must be aggressive to construction materials. Pump body and bracket: cast iron Impeller: brass Stainless steel shaft AISI 303 Ceramic graphite mechanical seal Closed, induction, self-ventilated electric motor Protection degree: IP44 Insulation class F Single-phase feeding 230V-50Hz, with motor protection Three-phase feeding 230/400V-50Hz Max working pressure: 6 bar Max temperature of pumped liquid: 90°C
