During the driving of the submersible pump 70, a repulsive force is generated due to various factors such as vibration of the motor, pinching of foreign substances in a rotating impeller or vane, and collision of suctioned foreign substances.

Part of the repulsive force acts in the direction in which the submersible pump 70 is lifted, so that the flange 60 increases the gap between the inlet 11 of the detachable body 10, and leaks occur through the increased gap.

The occurrence of water leakage causes energy loss and lowers the pump efficiency. When pumping at high pressure, water leakage may increase, resulting in an inability to pump water, and the continuous lifting phenomenon shortens the life of the product.

The support unit 40 blocks the lifting phenomenon due to the repulsive force in this way.

Referring to FIG. 4, the support unit 40 includes a first connector 41, a second connector 42, a connecting rod 43, and a fixture 44.
