[0002] The three-phase submersible sewage pump is a submersible pump that integrates a water pump housing, a motor and a sealing device. It is mainly used in industries such as industry, agriculture, mining, construction, and municipal engineering to discharge sewage and dirt containing solid particles and long-fiber substances. The submersible sewage pump is usually installed in a well or pond and connected to a power source with a cable. Most submersible sewage pumps are automatically controlled by a float switch through the water level.

[0003] The outlet of today's three-phase submersible sewage pump needs to be connected to the outlet pipe for water discharge. Traditional outlet pipe connections mostly use a sleeve connection method and are stabilized by a pipe clamp.
