Claims

[Scope of utility model registration request]

In a pump placed underwater, the stuffing box is located on the upper surface of the shaft sealing part of the stuffing box having an opening to eliminate the water suction system of the pump, is fixed to the motor shaft, and rotates in response to the rotation of the motor. 1. A submersible pump characterized in that a sand fringer having a structure that generates a water flow in a radial direction is installed.
