    摘要： In a magnetic coupling pump including a closed impeller, and a casing that houses the impeller in such a way that the impeller is rotatable around a rotation axis and movable in an axis direction in which the rotation axis extends, reduction in the rotational frequency of the impeller can be suppressed even if thrust balance collapses temporarily and the impeller and the casing come into contact with each other. A tapered surface (24) or (55) is formed in at least a portion of at least one of a surface (24) or (53) of the impeller (10) and a surface (66) or (86) of a pump casing (60) that faces each other in an axis direction (Da) so that the distance between both the faces varies gradually as it goes in a radial direction (Dr) perpendicular to the axis direction (Da).
