1. Submersible sewage pumps utilize a unique single or double-screw impeller structure, significantly enhancing the ability to pass solids. They can effectively handle fiber materials up to 5 times the pump's diameter and solid particles with a diameter approximately 50% of the pump's diameter.

2. The submersible sewage pump mechanical seal uses a new, hard and corrosion-resistant titanium carbide material, enabling the pump to run safely and continuously for over 8,000 hours.

3. Submersible sewage pumps feature a compact overall structure, small size, low noise, and significant energy-saving effects. They are easy to maintain, do not require a pump house, can be submerged in water for operation, and greatly reduce the construction cost.

4. The stainless steel submersible sewage pump features a high-precision anti-interference leakage detection sensor in the seal oil chamber, with a thermal sensor pre-installed in the stator winding for automatic motor protection.

5. Stainless steel submersible sewage pumps can be equipped with an automatic control cabinet to meet customer needs, providing automatic protection against leaks, electrical leakage, overload, and overheating, enhancing the product's safety and reliability.

6. The stainless steel submersible sewage pump with an air ball switch can automatically control the pump's start and stop according to the required liquid level, eliminating the need for constant supervision and offering great convenience in use.

7. Stainless steel submersible sewage pumps can be equipped with a dual-track automatic coupling installation system to meet customer requirements, offering greater convenience for installation and maintenance, eliminating the need for personnel to enter the sewage pit.

8. Submersible sewage pumps can be used across the entire head range without overloading the motor.

9. The submersible sewage pump comes in two different installation methods: fixed automatic coupling system and mobile free installation.
