Description
WQD10-36-2.2KW Aico Japan 3HP Sewage Submersible Pump: High-Pressure Professional Drainage
Bridge the gap between residential convenience and industrial power with the WQD10-36-2.2KW Aico Japan Sewage Submersible Pump. This high-performance unit is engineered for those who require significant vertical lift but only have access to standard Single-Phase (240V) power. With a robust 3HP (2.2KW) motor and a vertical head capacity of 50 meters, this pump is the ultimate solution for deep basement dewatering, septic tank management, and garden irrigation from deep reservoirs.
Built to rigorous Japanese engineering standards, the WQD series is designed to handle “dirty water” with ease. Whether you are clearing a flooded construction site, managing household sewage, or transferring silted water from a pond, this 2-inch outlet pump provides the reliability and mechanical force required for consistent, heavy-duty service.
The Aico Japan Engineering Advantage
The WQD10-36-2.2KW stands out in the 3HP class due to its specialized high-lift architecture:
-
Impressive 50M Vertical Lift: Specifically designed to overcome significant elevation, making it ideal for pushing waste water vertically from deep underground tanks to surface-level sewer lines.
-
Single-Phase 2.2KW Motor: Optimized for standard 220V–240V power, providing the high torque necessary to handle thick effluents without the need for specialized industrial three-phase wiring.
-
Non-Clog Vortex Impeller: Features a reinforced cast iron open impeller designed to create a powerful vortex that passes suspended solids and prevents clogging.
-
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 Efficiency for Domestic & Light Commercial Use
While many single-phase pumps struggle with height, the WQD10-36 is a high-lift specialist. Its internal hydraulic stages are optimized to maintain pressure over long vertical distances, ensuring that waste reaches its destination even from deep basement levels.
2. Rugged Cast Iron Construction
The entire pump housing is crafted from high-density gray cast iron. This provides the structural weight necessary to remain stable at the bottom of a tank and ensures the pump survives the abrasive materials and physical impacts common in drainage environments.
3. Integrated Thermal Overload Protection
To protect your investment, the 2.2KW 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. High-Velocity 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. User-Friendly Setup
Designed for practical use, this pump features a heavy-duty lifting handle and a standard plug-and-play single-phase configuration. It is easy to install in septic pits, sumps, or wells without the complexity of industrial control panels.
