PROBLEM TO BE SOLVED: To suppress occurrence of deviation in a circumferential direction of flow velocity of conductive fluid flowing an annular channel.SOLUTION: An electromagnetic pump 10 includes: a peripheral wall 22 having a cross-section having a substantially annular shape, extending in an axial direction and being a wall body defining an annular channel 20 where conductive fluid flows; coil sections 24 and 25 being provided adjacent to the peripheral wall 22 and forming a magnetic field in the annular channel 20 so as to generate electromagnetic force toward an axial direction outlet side to the conductive fluid flowing the annular channel 20. An annular channel inflow port 44 being an opening where the conductive fluid flows into the annular channel 20 is formed at a portion closer to an axial direction inlet side than the outside coil section 25 out of an outer wall 40 constituting a radially outside of the peripheral wall 22. The conductive fluid sucked from an inlet side pipe 5 passes through the annular channel inflow port 44 and flows into the annular channel 20.SELECTED DRAWING: Figure 1 |
