SHIYUAN 40M Solar Submersible Pump: High-Performance Water Lifting for Deep Wells
Upgrade your water management with the SHIYUAN 40M Solar Submersible Pump. Engineered for versatility and high-pressure performance, this 24V DC-powered pump is specifically designed to bridge the gap between shallow wells and deep boreholes. With a robust 40-meter maximum head (lift) and a significant flow rate, it is the ideal solution for medium-scale agricultural irrigation, reliable domestic water supply, and livestock watering in off-grid or remote locations.
The SHIYUAN 40M series utilizes cutting-edge Brushless DC (BLDC) motor technology, ensuring maximum energy conversion from your solar panels. By operating entirely on renewable energy, this pump eliminates the recurring costs of diesel and electricity, providing a sustainable, “set-and-forget” water solution that pays for itself in record time.
The 40M Professional Engineering Advantage
The SHIYUAN 40M pump is built to handle the rigors of deep-well operation:
-
Enhanced Lift Capacity: Designed to push water vertically up to 40 meters (131 feet), making it suitable for deeper water tables where standard pumps fail.
-
Intelligent Dry-Run Protection: Features an integrated sensor that automatically shuts down the motor if the water source runs dry, preventing overheating and extending the pump’s lifespan.
-
Advanced MPPT Compatibility: Optimized to work with MPPT (Maximum Power Point Tracking) controllers, ensuring the pump starts earlier in the morning and runs later into the evening.
-
Corrosion-Proof Materials: Every structural component is crafted from AISI304 stainless steel, providing total immunity to rust and chemical degradation in borehole environments.

Product Highlights
1. Optimized 24V High-Power Efficiency
Unlike smaller 12V models, the SHIYUAN 40M operates on a 24V system, allowing it to handle higher head pressures with ease. It is perfectly matched for a 400W–500W solar array (typically 2 x 250W panels in series), providing the torque needed for consistent, high-volume water delivery throughout the day.
2. Brushless DC (BLDC) Motor Excellence
Equipped with rare-earth permanent magnets, the BLDC motor is significantly more efficient than traditional brushed motors. It runs cooler, operates quietly, and—most importantly—has no carbon brushes to wear out, virtually eliminating motor-side maintenance for years.
3. Industrial Grade 304 Stainless Steel
From the outer shell to the internal rotor, the pump is built using food-grade 304 stainless steel. This ensures that the water remains uncontaminated and the pump body remains structurally sound, even when submerged in mineral-heavy or slightly acidic “hard” water.
4. Sand-Resistant Impeller System
SHIYUAN utilizes laser-welded stainless steel impellers and a fine-mesh suction strainer. This design is specifically engineered to handle water with a higher sand content (up to 150g/m³), preventing the internal clogs and abrasive wear that often destroy inferior plastic pumps.
5. Safe & Smart Circuitry
The pump includes built-in safeguards against over-voltage, under-voltage, and over-current. When combined with the included floating switch, the system becomes fully automated—filling your tank when low and stopping when full, all without human intervention.
Primary Applications
-
Commercial Agriculture: Perfect for larger drip irrigation kits and greenhouse water management.
-
Community Water Projects: A reliable source for small villages, schools, and clinics in off-grid regions.
-
Livestock & Ranching: Delivering steady water to large troughs for cattle, sheep, and goats.
-
High-Lift Domestic Use: Pumping from deep wells to elevated hilltop tanks or multi-story buildings.
