Unplanned pump downtime caused by rags, sanitary wipes, stringy debris, and fibrous solids is one of the biggest challenges in industrial and municipal wastewater management. The ASWQ Submersible Cutting Pump is engineered specifically to eliminate clog-related failures at the source.
By combining a high-torque submersible motor with a precision alloy cutting mechanism, the ASWQ series shreds tough solids before they enter the pump casing, delivering continuous, maintenance-free fluid transport in wet well lift stations, commercial processing plants, and municipal treatment facilities.
ASWQ Submersible Cutting PumpTechnical Highlights & Engineering Design
1. Hardened Cutting Mechanism
The ASWQ series features a high-hardness cutter disk and tungsten carbide-tipped impeller. Rotating at high speed against the serrated cutter plate, it instantly shears synthetic fibers, textiles, plastics, and organic waste into fine slurry—preventing impeller binder and line blockages.
2. Non-Clogging Hydraulic Performance
Designed with a semi-open hydraulic profile, the pump maintains high liquid velocity and stable discharge head even when handling heavily contaminated slurries with high solid concentrations.
3. Dual Mechanical Seals & IP68 Submersible Motor
-
Mechanical Seal: Double-end silicon carbide to tungsten carbide mechanical seal housed in an oil chamber for maximum wear resistance.
-
Motor Insulation: Heavy-duty copper-wound motor rated Class F/H insulation with built-in thermal overload protection.
-
Ingress Protection: Full IP68 waterproof rating for continuous submerged operation.
4. Modular Discharge & Slide Rail Compatibility
Available with standard flanged discharge connection (DN50 to DN200) and compatible with guide rail auto-coupling systems, allowing quick installation and surface retrieval without draining the wet well pit.
