The Differences Between Submersible Pumps and WQ Type Submersible Sewage Pumps:

1. Different media handled

General submersible sludge pumps are non-clog sewage pumps, handling water quality in poor condition, which may contain highly corrosive substances. The transported medium consists of feces or liquids containing fibrous materials that tend to tangle or clump, as well as solid particles like paper shreds. The operating conditions for submersible pumps are relatively simple, primarily transporting clean water. As for the material requirements of the product, they are easier to select compared to sewage pumps.

2. Structural Differences

Due to the differences in the media they handle, submersible slurry pumps and submersible pumps vary. Submersible slurry pumps feature a large-channel impeller structure, which can effectively pass solid particles up to 50% of the pump's diameter, allowing for the processing of materials like long fibers and paper shreds. This significantly enhances the pump's ability to handle debris, resulting in high anti-clogging and reliability. Conversely, submersible pumps have a simpler structure compared to slurry pumps.

3. Varying Application Scope

Submersible pumps are used in wastewater transportation/discharge, sponge cities, pump station drainage, floodwater discharge prevention in urban areas, and urban wastewater treatment. They are also applied in industrial wastewater discharge fields such as petrochemicals, mining, cement factories, and construction site wastewater discharge, generally used in environments like sump pits. Submersible pumps are employed for deep well water extraction, irrigation, and offshore platforms, and can be used as pump systems.
