The GW‑type pipeline sewage pump is a next‑generation pump developed by integrating advanced foreign technologies with the specific operating characteristics of domestic pumps. Its hydraulic design is identical to that of the WQ‑type sewage pump. It boasts significant energy‑saving performance, anti‑entanglement capabilities, and a clog‑free operation. Moreover, it delivers exceptional results when handling solid particles and long‑fiber waste.

This pump series features a unique impeller design and a new‑type mechanical seal, enabling it to efficiently handle fluids containing solids and long fibers. Compared with conventional impellers, this pump employs a single‑channel impeller that resembles a bent pipe of the same cross‑sectional size, offering excellent flow characteristics. Coupled with a well‑designed volute, the pump delivers high efficiency, and its impeller has undergone rigorous balancing tests, ensuring vibration‑free operation.

This pump boasts advanced and well‑established hydraulic performance; testing has confirmed that all performance parameters meet the relevant standards. Since its market launch, it has been widely acclaimed by users for its unique efficacy, reliable operation, and consistent quality.

Product Features

1. The pump is a vertical, single-suction, single-stage centrifugal sewage pump. Its inlet and outlet centerlines lie on the same horizontal plane, and its inlet and outlet flanges are identical, making installation and removal extremely convenient. It occupies a small footprint and can be installed at any point in the pipeline, just like a valve.

2. The pump is directly coupled to the motor on a common shaft, making it an electromechanical integrated product with a compact structure and stable performance.

3. Featuring a large‑flow‑path, anti‑clogging hydraulic design, this pump significantly enhances its ability to pass debris, effectively handling fibrous materials up to five times the pump’s nominal diameter and solid particles with diameters of approximately 50% of the pump’s nominal diameter.

4. The design is well-optimized, the accompanying motor is appropriately matched, resulting in high efficiency and significant energy savings.

5. The mechanical seal is made of hard, wear-resistant tungsten carbide, offering durability and excellent wear resistance, enabling the pump to operate safely and continuously for over 8,000 hours.

6. Advanced hydraulic performance, high overall efficiency, and low operating noise.

7. By installing a protective guard on the motor’s fan end, the entire unit can be operated outdoors without requiring a dedicated machine room, thereby significantly reducing capital construction costs.

8. Operate within the rated performance range to ensure the motor is not overloaded.

Product Application Scenarios

1. The discharge of heavily polluted wastewater from factories and commercial establishments.

2. Drainage system of urban wastewater treatment plants.

3. Wastewater pumping station in the residential area.

4. Civil defense system drainage station.

5. Wastewater discharge from hospitals and hotels.

6. Municipal engineering and construction sites.

7. Exploration and auxiliary equipment for mining operations.

8. Biogas digesters in rural areas for agricultural irrigation.

9. The water supply system of the municipal water treatment plant.

Pump Operating Conditions

1. The medium temperature shall not exceed 60°C, with a specific gravity of 1.0–1.3 kg/dm³ and a pH value within the range of 5–9.

2. The pump and motor are integrated into a single unit; therefore, the ambient temperature around the pump must not exceed 40°C, the altitude must be no greater than 1,000 m, and the relative humidity…

Not exceeding 95%.

3. In general, the pump must be operated within its rated head range to ensure the motor is not overloaded. If operation over the full head range is required, this should be specified at the time of order.

Please specify separately to facilitate manufacturing by the supplier.

4. During operation, the pump motor current must not exceed the motor’s rated current.
