According to different media used, submersible pumps can be roughly divided into three categories:

1. Clean water submersible pump

2. Sewage submersible pump

3. Sea water submersible pump (corrosive).

The basic parameters of submersible pumps include flow, head, pump speed, supporting power, rated current, efficiency, water outlet pipe diameter, and so on.

The submersible pump is composed of a control cabinet, submersible cables, pumping pipes, submersible electric pumps and submersible motors.

The main purpose and scope of application of submersible pumps include mine rescue, construction drainage, water and agricultural drainage and irrigation, industrial water circulation, urban and rural residents' water supply, and even emergency rescue and disaster relief.
