【Task】 In order to obtain a high-temperature and high-pressure and leak-free pump for transporting corrosive heavy solutions, it has a corrosion-proof structure, high-temperature and high-pressure specifications, leak-tight structure for toxic gases and solutions, and heavy-liquid transport specifications. It was necessary to maintain the pump itself against solution solidification due to failure of temperature control of the transport solution. [Solution] An impeller, a rotating shaft, a magnet for rotationally driving the rotating shaft, and a sleeve that supports the rotating shaft are provided in the rear casing of the pump, and an impeller coupled to the rotating shaft is provided in the front casing of the pump, In the high-temperature and high-pressure corrosion-resistant pump that sucks the mixed heavy liquid from the front casing inlet with the impeller and discharges it from the front casing outlet, tantalum is used for the front, rear casing, impeller and rotating shaft of the wetted part, and the welding thereof Magnet coupling type pump using ceramics for material, sleeve, bushing and thrust.
