ABSTRACT:
A vertical shaft type pump including a bearing device in which water in the pump is utilized as lubricating water without supplying water to the bearing from the outside of the pump, thereby repeatedly conducting no-load operation in the air (in such a state that water is not pumped) stably for a long period of time. In the pump, a water storage tank upwardly opened is fixed to a rotary shaft, and the lubricating water (the water in the pump) is retained within the water storage tank so that the bearing is operated while being always soaked in the lubricating water. Also, foreign substances in the water storage tank are mixed with the water without deposition, and the water containing the foreign substances is replaced by the newly pumped water.
