Such a vertical pump is generally constructed such that a casing constituting a vertical pump is submerged in an inner side of a tank in which a fluid is stored and then the fluid is sucked through the rotation of the impeller provided inside the casing and then discharged in a direction opposite to the direction in which the pump is sucked .

For example, as described in the documents (1) and (2), the fluid is smoothly conveyed in the direction of the inlet and outlet provided in the casing through the rotation of the impeller and the rotation shaft rotatably coupled to the inside of the casing .

However, in the conventional vertical pump as described above, when the structure of the bearing and the seal to be coupled for smoothly rotating the rotary shaft installed inside the casing is worn or damaged due to rotation of the rotary shaft for a long period of time, There was a problem that the fluid could be contaminated, and the function of the rotary shaft was deteriorated, so that the vertical pump failed to function.

In addition, there has been a problem that the inherent function of the vertical pump is deteriorated due to a problem that various pollutants are introduced into the bearing coupled to the rotary shaft and the bearing is damaged.
