3.The working performance is different

Submersible pump general circulation coefficient is very small, and the working pressure difference is very small. For example, the general diameter of the submersible pump diameter of 15 than 15-valve ball valve is much smaller. Submersible pump drive is through the electromagnetic coil, relatively easy to be damaged by voltage shock. Equivalent to the role of the switch is to open and close the two roles.

Sewage pump drive is generally used motor, more resistant to voltage shock. Submersible pump is fast opening and fast closing, generally used in small flow and small pressure, the required switching frequency of the local sewage pump and vice versa. Sewage pump valve opening can be controlled, the state has on, off, half open halfway, you can control the flow of media in the pipeline submersible pumps fail to meet this requirement. Submersible pump can be reset when power cut, while sewage pump need to add reset device if with this function.
