Although sewage pumps and dirty water pumps have similarities in handling unclean liquids, their uses and designs are different. The specific differences are as follows:
1. Treatment medium
Sewage pump:
Specially used to treat sewage containing solid impurities (such as feces, fibers, paper towels, etc.). Usually used in household, industrial, municipal sewers and other scenarios. It has higher requirements for the passability of particles, and anti-clogging is considered in the design.
Dirty water pump:
Generally used to treat dirty water containing a small amount of particles or suspended matter, such as rainwater, light muddy water, etc., and is not suitable for treating sewage containing larger particles or fibrous impurities.
2. Design features
Sewage pump:
Equipped with anti-clogging impellers or cutting devices, it can handle large particles or long fiber impurities. Common designs include single-channel or multi-channel impellers, and even with built-in cutting functions.
Dirty water pump:
The impeller structure is relatively simple, mainly treating low-concentration dirty water, the diameter is usually small, and the ability to handle impurities is limited.
3. Application scenarios
Sewage pumps:
Septic tanks, sewage pipe networks.
Industrial wastewater treatment.
Heavy sewage discharge from restaurants or commercial areas.
Dirty water pumps:
Basement, garage drainage.
Agricultural irrigation or light drainage.
Drainage emergency after heavy rain.
4. Price and maintenance
Sewage pumps:
Due to the more complex design and stronger adaptability, the price is higher, and regular inspections are required to prevent clogging.
Dirty water pump:
Simple structure, relatively cheap price, low maintenance cost, but not suitable for high-concentration sewage scenarios.
In short, sewage pumps handle "heavy pollution" sewage and are suitable for complex sewage discharge environments; while dirty water pumps handle "light pollution" dirty water and are more suitable for ordinary drainage needs. Choosing the right pump according to the purpose can improve efficiency and reduce the cost of use.
