Single impeller centrifugal electro pumps specifically designed to obtain high capacities in relation to medium-low pressures (and outputs). The design of the pump body and impeller, characterized by large passage, make these pumps suitable to pump both clean water and liquids with a moderate load of impurities, as long as these are not aggressive of the construction materials. Cast iron PUMP BODY and BRACKET; stamped brass alloy IMPELLER; stainless steel SHAFT; ceramic-graphite MECHANICAL SEAL. Closed, self-ventilated induction ELECTRIC MOTOR; Insulation class F, IP44 protection. Standard manufacture: 230 V - 50 Hz single-phase k, with built-in thermal protection; 230/400 V - 50 Hz three-phase, with electric protection to be provided by the user. Max temperature of pumped liquid: 90°C; max working pressure: 6 bar.
