There are three types of submersible pumps, one is a well-used submersible pump, the other is a magnetic levitation pump, and the other is a submersible sewage pump. The main features of the well-used submersible pump include the motor and the pump body, which is safe and reliable when submerged in the water. There are no special requirements for the well pipe and the pumping pipe. It is very convenient in installation, maintenance and use, and the area is small. As long as the operation is carried out reasonably, the service life can be guaranteed.
