Document Type and Number:

WIPO Patent Application WO/2012/108475

Kind Code:

A1

Abstract:

A magnetically driven, coupling type pump configuration provided with an attachment/detachment mechanism capable of simple and reliable positioning and affixation. A pump configuration is configured in such a manner that a pump unit (10) is positioned in the thrust direction by surface contact occurring when the protrusion (11) of the pump unit (10) is inserted into a predetermined position of the recess (31) of a drive motor unit (30), and that the pump unit (10) is positioned in the radial direction by the contact between the outer peripheral surface of the protrusion (11) and the inner peripheral surface of the recess (31). The pump configuration is provided with: claw sections (15) protruding from the outer peripheral surface of the pump unit (10); engagement sections (32) protruding upward from the outer periphery of the upper surface of the drive motor unit (30) so that, when the pump unit (10) is rotated while the protrusion (11) is inserted to a predetermined position of the recess (31), the engagement sections (32) are engaged with the claw sections (15) to prevent the claw sections (15) from moving upward; and a lock mechanism (50) for retaining the pump unit (10) at the position at which the claw sections (15) and the engagement sections (32) are engaged with each other.
