Magnet pump
 A magnet pump is provided with a heat insulating member arranged between a shaft serving as the rotating axis and an impeller or a magnet can, heat conduction cut-off grooves on a heat conducting path, and a safety lock mechanism. These elements ensures to prevent frictional heat, even if generated due to abnormal operating conditions such as a non-load operation, from being conduted to parts with lower heat resistivity such as the impeller and the casing, deflection in rotation caused by looseness due to thermal expansion, and accordingly the magnet pump is protected from damages.
