Sewage pumps and submersible pumps are common equipment in engineering. There is a difference between the two. So what is the difference between sewage pumps and submersible pumps?

Both sewage pumps and submersible pumps need to be submerged to work. To a certain extent, sewage pumps are a kind of submersible pumps, but there are still differences between the two:

1.Different media handled

Generally, the water quality treated by sewage pumps is relatively poor.The water quality may contain highly corrosive and the conveying medium is a medium containing solid particles such as fibers and paper scraps in feces or liquids.The conveyed medium contains fibrous materials that are easy to entangle or bunch.sewage pump is generally used for normal temperature slurry, PH value is between 6~8, the volume ratio of liquid to solid is below 2%, and the pump head is an open flow channel,which will not be sucked by solid particles and fibrous debris. Blocking, so it is also called non-blocking sewage and sewage electric pump; while the work of submersible pump processing is relatively simple, the transport medium is mainly clean water,the content of insoluble solid impurities in the water does not exceed 0.1%, the particle size is not greater than 0.2mm, and the PH value is Within the range of 6.5~8, it is easier to choose the material requirements of the product than the sewage pump.

2.Different structure

Because of the difference in the media that it handles, there is a difference between sewage pumps and submersible pumps. Sewage pumps need technology to deal with solid particles such as long fibers and paper scraps.Therefore, anti-blocking and reliability are important factors for the quality of sewage pumps.The drive of the sewage pump is generally turned on or off by a motor.It takes a certain amount of time to complete the action. It can be adjusted. The sewage pump has an open impeller to prevent clogging;Compared with the sewage pump, the submersible pump has a much simpler structure.The submersible pump is driven by a coil and can only be turned on or off. The switching time is short. The submersible pump is a closed impeller.

3.Different application range

Sewage pumps are used in sewage transportation/discharge, sponge cities, transportation of industrial wastewater, pumping station drainage, urban flood prevention and discharge, etc;The submersible pump is an important equipment for deep well water lifting. When in use, the entire unit submerges into the water to extract groundwater to the surface.It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, and can also be used for fountain landscape.
