Abstract
A magnetic-drive coupling pump configuration including an attachment/detachment mechanism allowing simple and reliable positioning and fixation is provided. Thrust-direction positioning and radial-direction positioning are achieved, respectively, by surface contact of a convex portion of a pump unit () inserted up to a predetermined position in a concave portion () of a drive motor unit (), and contact between an outer circumferential surface of the convex portion () and an inner circumferential surface of the concave portion (). A claw () protruding on the outer circumferential surface of the pump unit (), an engaging portion () protruding upward from an upper outer circumferential portion of the drive motor unit () to restrict, by engagement, claw upward movement when the pump unit () is rotated with the convex portion () inserted up to the predetermined position in the concave portion (), and a locking mechanism () holding the pump unit () at an engagement position of the claw () and the engaging portion () are included.
