What kind of Submersible Sewage Pump is the most useful

  •   How Submersible Sewage Pump works

      The Submersible Sewage Pump will automatically turn on; this is caused by the pressure sensor or float activator in the system. When water accumulates in the pit or around the base and generates a greater pressure than air, the pressure sensor will activate, prompting the pump to start working. Similar to the one in the toilet tank, the float activator has a ball that floats on the surface of the water and moves its arm as the water level rises.

      After the sensor or arm tells the pump to start working, the centrifugal pump starts to move water. When the pump is turned on, a screw or fan-shaped device called an impeller rotates. The rotating impeller uses centrifugal force to push the water to both sides of the pipe, forming a low-pressure zone in its center. The water in the puddle rushes to the gap, and the rotating action of the impeller pushes the water out of the pipe. Technology aside, the process is similar to draining water from a sink or bathtub but requires an electric assistant.
