PROBLEM TO BE SOLVED: To provide a magnetic driving pump in which a rotational speed of an impeller corresponding to a rotational speed of an inductor can be set to a desired rotational speed different from that of the inductor and a pump discharging amount can also be set to "0".SOLUTION: This invention comprises a magnet unit 3 reciprocated and moved along a driving shaft 2 by a first moving mechanism 4 while being synchronously rotated with the driving shaft 2, a first gear 5a provided with an inductor 6 that can be coaxially rotated with the driving shaft 2 and the rotation of the magnet unit 3 is transmitted/shut off by approaching/moving away of the magnet unit 3, a second gear 5b engaged with the first gear 5a to rotate an output shaft 7 in parallel with the driving shaft 2, an impeller 8 integrally arranged with the output shaft 7, a partitioning wall 9 for water-tightly defining the magnet unit 3 and the inductor 6, and a stopping mechanism 25 for stopping rotation of the output shaft 7 when a distance between the magnet unit 3 and the inductor 6 is expanded and a rotational speed of the output shaft 7 is decreased.SELECTED DRAWING: Figure 1 |
