Claims

[Claims for Utility Model Registration] 1. The main shaft is divided into a driving shaft and a driven shaft, and both sides of the driven shaft, which is rotatably supported by a bearing provided in the pump casing, have a tapered shape. The boss portion has a non-circular cross-sectional shape, and each of these boss portions has a protruding shaft portion having a thread of the same shape, and a magnet that faces the magnet provided on the drive shaft side across a partition wall. A wheel body comprising: is fitted to one boss portion of the driven shaft; an impeller disposed in a fluid chamber connecting the suction port and discharge port of the pump casing is fitted to the other boss portion of the driven shaft; A magnetic pump further characterized in that the wheel body and the impeller are tightened by nut-shaped members having the same shape screwed into the shaft portions protruding from the respective boss portions. 2. A fluid passage communicating between the fluid chamber and the internal space of the partition wall is provided in the pump casing, and
2. The magnetic pump according to claim 1, further comprising a strainer provided at the entrance of the fluid passageway to prevent the flow of solid matter.
