Product Overview
AS/AV Cutting Submersible Sewage Pump is a heavy-duty submersible sewage pump equipped with an integrated cutting mechanism, designed for pumping sewage containing fibrous and solid materials.
It prevents clogging caused by long fibers, textiles, and debris by shredding solids before discharge.
It is widely used in municipal sewage systems, building wastewater drainage, and industrial effluent transfer requiring anti-blocking capability.
Model Designation
Applications
• Municipal sewage lifting stations handling household wastewater with textile and fibrous content
• Basement and underground drainage systems where gravity discharge is not feasible
• Industrial wastewater pits containing soft solids and organic waste
• Residential community sewage collection wells with high clogging risk
Engineering Advantages
• Integrated cutting impeller and cutter plate structure ensures pre-discharge shredding of fibrous solids, reducing blockage risk and maintaining hydraulic continuity
• Submersible motor design with compact structure enables direct installation in sump pits without additional priming system
• Hardened cutting components improve wear resistance under continuous sewage duty

How to Select a Pump Model
- Determine required flow rate and total dynamic head based on sewage lifting height and pipeline losses.
- Confirm solid content and fiber length to verify suitability of cutting mechanism capacity.
- Check sump depth and installation method (auto-coupling or free-standing).
- Verify power supply conditions including voltage and frequency.
Engineering Notes
• Designed for intermittent or continuous sewage duty under submersible conditions
• Not suitable for pumping abrasive slurry with high sand concentration
• Recommended to ensure adequate sump volume to avoid excessive start-stop cycles
• Cutting components should be periodically inspected under heavy fiber loading
Compliance & Quality Assurance
• Hydraulic performance test before delivery
• Insulation resistance and motor winding test
• Mechanical seal leakage inspection
• Material traceability for major components
Safety Notice
• Do not operate under dry-running condition
• Ensure full submersion before startup
• Disconnect power before maintenance
• Avoid operating beyond rated current
