Description
WQD10-60-4KW Aico Japan 5.5HP Sewage Submersible Pump: High-Pressure Waste Water Solution
Efficiency meets industrial power in the WQD10-60-4KW Aico Japan Sewage Submersible Pump. This specialized high-head pump is designed for vertical lift challenges where standard sewage pumps fall short. With a robust 5.5HP (4KW) three-phase motor and a powerful vertical lift capacity of 80 meters, this unit is the definitive choice for dewatering deep basements, construction pits, and industrial effluent systems that require significant pressure.
Built to rigorous Japanese industrial standards, the WQD series is engineered for durability in harsh underwater environments. Whether you are managing municipal waste, clearing a flooded foundation, or transferring agricultural runoff, this 2-inch outlet pump provides the reliability and mechanical force required for continuous, heavy-duty service.
The Aico Japan Engineering Advantage
The WQD10-60-4KW leads its class in high-lift sewage technology through its reinforced internal architecture:
-
Powerful 80M Vertical Head: Specifically engineered to push waste water vertically up to 80 meters, making it ideal for discharge from deep underground parking levels and construction shafts.
-
Three-Phase 4KW Motor: The industrial 380V–415V motor delivers stable, high-torque power, ensuring the pump can handle the resistance of high-viscosity sludge and debris-laden liquids.
-
Hardened Non-Clog Impeller: Features a reinforced cast iron open-vortex impeller designed to shred and pass solids without compromising hydraulic efficiency.
-
Dual Mechanical Seal Protection: Equipped with an Italian-style double-mechanical seal housed in an oil chamber, providing a watertight barrier that protects the motor from the corrosive nature of wastewater.

Product Highlights
1. High-Lift Performance Specialty
While most submersible pumps prioritize volume over height, the WQD10-60 is a high-lift specialist. It is designed to maintain consistent pressure over long vertical distances, ensuring that waste is successfully discharged from deep elevations to the main sewer line.
2. Rugged Cast Iron Construction
The entire pump housing is crafted from high-density gray cast iron. This provides the necessary structural weight for stability at the bottom of a pit and ensures the pump survives the abrasive and corrosive chemicals found in industrial and agricultural waste.
3. Integrated Thermal Overload Protection
To safeguard your investment, the 4KW motor includes internal thermal sensors. If the pump encounters a blockage or the motor temperature exceeds safe limits, the system automatically cuts power to prevent winding burnout, drastically extending the machine’s life.
4. Optimized 2-Inch Discharge
The 2-inch (50mm) outlet is sized for high-velocity discharge. This diameter ensures that fluid moves fast enough to keep solids in suspension, preventing sedimentation and clogging in your discharge piping during long vertical runs.
5. Ease of Maintenance
Despite its industrial capacity, the WQD10-60-4KW is designed for practical field use. It features a heavy-duty lifting handle for secure deployment and an accessible suction strainer that can be cleared of large debris without dismantling the motor housing.
