The treated medium is different. Generally, the water quality treated by sewage pump is in bad condition, and the water quality may contain highly corrosive fibers that are easily entangled or bunched. For example, the transport medium is feces or liquid, which contains solid particles such as fibers and paper scraps. However, the working condition of clean water pump is relatively simple, and the medium to be transported is clean water, so the material requirements of products are simpler to select than sewage pumps.
The structure is different, because the media they handle are different, so there are also great differences in structural planning. Sewage pumps need skills to dispose of solid particles such as long fibers and paper scraps, so anti-blocking and reliability are important factors for the quality of sewage pumps. Usually, in order to avoid debris blocking the pipeline, the flow channel is generally planned to be very wide.
The clean water pump is composed of a motor and a water pump, which is mainly used to transport clean water. Because there are no impurities and particles in the transport medium, the gap between the impellers of the clean water pump is small, which has a disadvantage: if sundries are generated in the operation process and simply blocked in the impeller, the impeller will not rotate, and there will be problems.
Pumps with different application ranges are used to transport industrial wastewater, pump station drainage, urban flood control water discharge and other fields; The fresh water pump is used in deep well water intake, agricultural irrigation, ocean channels and other fields. With the continuous development of pump skills, fresh water pump and sewage pump with single function are gradually replaced by submersible sewage pump with sewage/fresh water.
