    摘要： A magnet pump has a magnet coupling for magnetically coupling an inner ring yoke and an outer ring yoke so as to magnetically transmit a torque from driving part to driven part of the pump to rotate the driven part. The magnet pump comprises magnetized magnet pieces bonded to the outer peripheral surface of the inner ring yoke and magnetized magnet pieces bonded to the inner peripheral surface of the outer ring yoke; non-magnetic cylindrical covers covering the surface of the inner ring yoke carrying the magnet pieces and the surface of the outer ring yoke carrying the magnet pieces, respectively; and mold resin parts filling the gap between the surface of the inner ring yoke and the associated non-magnetic cylindrical cover and the gap between the surface of the outer yoke ring and the associated non-magnetic cylindrical cover. Also disclosed are a method of producing the magnet pump in which the non-magnetic cylindrical covers are used as molds, and a nuclear reactor equipment in which the magnet pump is used as a coolant circulation pump.

    摘要： A multi-stage diffuser-type centrifugal pump suitable for feeding under pressure a low-temperature fluid such as a liquefied gas. Stages are respectively provided between adjacent ones of impellers provided in a plurality of stages. A cylindrical stage casing is provided in such a manner as to surround the stages, a sealant is provided between each stage and the stage casing to form a channel flow on an inner peripheral surface of the stage casing for flow from an upstream-side impeller to a downstream-side impeller. In addition, the sealant has a coefficient of thermal expansion which differs from the coefficient of thermal expansion of the stage and the stage casing.
