ABSTRACT:
A centrifugal pump for use in pumping hot liquids under pressure. A rotatable shaft, having an impeller at its lower end, is positioned along the axis of a generally cylindrical pump casing. The pump casing has a suction nozzle at its lower end, and a discharge nozzle near the upper end. A cylindrical outer shell surrounds the shaft within the casing, and a flange on the outer shell is secured to the top of the casing. A cylindrical inner shell is positioned inside the outer shell, surrounding the shaft, and a space is formed between the inner shell and the outer shell. The space provides an effective thermal barrier to protect the shaft. A bearing assembly for the shaft is secured to the inner shell, and a cooler is positioned between the bearing assembly and the impeller, thereby protecting the bearing assembly from the heat of the fluid being circulated by the pump. Seals are inserted within the inner shell above the bearing assembly, and these seals confine the high-pressure liquid within the pump.
