Overview of the YW Submersible Sewage Pump

The YW-type submersible sewage pump without clogging is a next-generation pump developed by integrating advanced foreign technologies with the specific operating characteristics of domestic pumps. It boasts significant energy-saving performance, anti‑entanglement features, and complete blockage‑free operation, delivering exceptional efficiency when handling solid particles and long‑fiber waste.

This pump series features a unique impeller design and a new type of mechanical seal, enabling it to efficiently handle fluids containing solid particles and long fibers. Compared with conventional impellers, this pump’s impeller adopts either a single‑channel or dual‑channel configuration, resembling a bent pipe of the same cross‑sectional size, which provides excellent flow‑through performance. Coupled with a well‑designed volute, the pump delivers high efficiency and superior hydraulic performance. Furthermore, the impeller has undergone static and dynamic balancing tests, ensuring vibration‑free operation.

This pump boasts advanced, proven 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.

4. Drainage system of urban wastewater treatment plants;

5. Civil defense system drainage stations and water supply facilities of the municipal waterworks;

6. Discharge of severely polluted wastewater from factories and commercial establishments;

7. Exploration and auxiliary equipment for mining operations;

8. Biogas digesters in rural areas for agricultural irrigation.

Product Features of the YW Submersible Sewage Pump

1. Featuring a large‑flow, 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 30% of the pump’s inlet size.

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

3. The mechanical seal employs a double‑stage tandem configuration, with a hard, corrosion‑resistant tungsten carbide material that offers exceptional durability and wear resistance, enabling the pump to operate safely and continuously for over 8,000 hours.

4. The pump features a compact structure, small footprint, easy mobility, and simple installation.

5. An automatic liquid-level control cabinet can be optionally equipped to meet user requirements, enabling the pump to start and stop automatically in response to changes in the desired liquid level, eliminating the need for dedicated supervision and ensuring extremely convenient operation.

6. The pump features a vertical design; during operation, the pump body is submerged in the liquid, ensuring easy priming and eliminating the need for venting or vacuum‑priming. It also boasts leak‑free performance and can be installed at submersible depths ranging from 0.5 to 7 meters.

7. The shaft coupling structure is advanced and reliable; the pump and motor are connected via a coupling, and the pump shaft is manufactured to precise dimensions, ensuring smooth operation and providing ample safety margins.

8. Ensure that the motor operates within its rated head range without overload.

9. The pump is available in both single-pipe and double-pipe configurations, and the mounting brackets can be installed using either a round plate or a square plate.

Operating Conditions for YW Submersible Sewage Pumps

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

2. 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 so that the manufacturer can accommodate it during production.

3. During operation, the pump motor current shall not exceed the motor’s rated current.

4. If there are specific requirements regarding temperature, media, or other factors, please specify the detailed characteristics of the conveyed medium when placing your order to facilitate manufacturing by the supplier.
