WQG Series Cutting Pumps

The WQG Series Sewage Cutting Pump features a unique spiral structure with sharp-edged cutter design. While maintaining high hydraulic efficiency (exceeding industry standards), it delivers superior cutting performance for shredding fibrous materials such as straw, cotton, cloth, and disposable diapers, ensuring smooth discharge of fragmented debris.

1、Cutting-Type Sewage Pump: Designed specifically for cutting and conveying sewage and solid waste (excluding special applications).

2、Full-Head Operation with Low Energy Consumption: Optimized power curves validated through testing reports.

3、Application Scope: Suitable for shallow water depths (≤25 meters) with high-flow, medium-to-low head requirements.

4、Tool-Free Cutter Plate Design: Enables rapid disassembly and replacement of cutter plates.

5、Customizable Cutter Types: Two primary cutter plate configurations available:

• Municipal Type: For urban sewage treatment.
• Livestock Farming Type: Engineered for high-solids-content wastewater in agricultural settings.

6、High-Hardness Cutting Components: Cutter materials with Rockwell hardness ≥48HR. Special materials available upon request.

• Pump Housing: HT200 gray cast iron.
• Pump Body: HT250 gray cast iron.
• Cutting Components: Alloy steel with Rockwell hardness ≥48HR.
• Cable: Heavy-duty rubber-sheathed cable (brand: Shangshang Group, China).
• Bearings: Domestic or optional imported brands.
• Mechanical Seals: Domestic graphite-silicon carbide seals or optional imported/composite brands.

Efficiency & Anti-Clogging Performance:

While the "high-efficiency + non-clogging" features may seem idealized, extensive field applications and laboratory tests confirm that the WQG Series Sewage Pump outperforms all domestic alternatives in both hydraulic efficiency and anti-clogging reliability.

General Safety Precautions

• Pre-Use Inspection: Check for cable damage before operation.
• Damage Assessment: Inspect the pump for leaks, physical damage, or mechanical jams caused during transportation.
• Power Connection: Connect power supply to a protected control cabinet.
• Safety Distance: Maintain a 15-meter clearance for personnel and livestock during operation.
• Prohibited Use: Never operate the pump in the same water body as humans or animals.
• Technical Support: Contact our sales team or toll-free service hotline for operational queries.

• Installation Height: Position the pump at least 25 cm above the pool/base bottom.
• Avoid Hard Objects: Prevent ingestion of stones, screws, or nails to prolong cutter lifespan.
• Cutter Replacement: Ensure impeller-to-cutter plate clearance is maintained between 0.1–0.25 mm after replacement.
• Fluid Compatibility: Operate exclusively in water-based, flowable liquids.
• High-Solid Content: Add water to dilute viscous sludge before startup if fluidity is limited.
