SHIYUAN 50M Solar Submersible Pump: High-Lift Water Security for Deep Boreholes
Master your water supply with the SHIYUAN 50M Solar Submersible Pump. Engineered for durability and high-vertical lift, this 24V 600W powerhouse is the flagship solution for deep wells and boreholes where standard pumps fall short. With a maximum head of 50 meters (165 feet), it is designed to deliver a consistent, high-volume water supply to medium-sized farms, rural communities, and large households in off-grid locations.
Powered by a high-efficiency Brushless DC (BLDC) motor, the SHIYUAN 50M maximizes every watt of solar energy harvested. By replacing expensive diesel generators and eliminating monthly electricity bills, this pump provides a sustainable, zero-operating-cost water solution that empowers your independence and pays for itself within the first two years of use.
The 50M Professional Series Advantage
The SHIYUAN 50M is built for high-demand environments and deep-well reliability:
-
Deep Well Specialization: Engineered to push water vertically up to 50 meters, making it perfect for properties with lower water tables.
-
Superior Flow Rates: Capable of moving up to 3,500 liters per hour, ensuring your storage tanks stay full even during peak demand periods.
-
Intelligent Inbuilt Controller: Features an integrated voltage stabilizer and MPPT (Maximum Power Point Tracking) technology to optimize performance during low-light mornings or cloudy afternoons.
-
Industrial Resistance: Crafted entirely from AISI304 stainless steel, providing total immunity to corrosion in mineral-heavy or borehole water.

Product Highlights
1. 600W High-Torque BLDC Motor
The heart of this pump is a 600W Brushless DC motor utilizing rare-earth permanent magnets. This design offers up to 50% more efficiency than traditional brushed motors. With no carbon brushes to replace and a cool-running design, the motor ensures years of maintenance-free operation.
2. Advanced Multi-Stage Impeller System
The SHIYUAN 50M utilizes precision laser-welded stainless steel impellers. This multi-stage design is specifically balanced to provide the high pressure needed for a 50-meter lift while remaining resistant to the abrasive effects of silt and sand often found in new boreholes.
3. Rugged All-Stainless Steel Body
Constructed from food-grade 304 stainless steel, the pump body and rotor are built to last a lifetime submerged. This prevents the rust and structural degradation that can cause cheaper plastic-bodied pumps to fail within their first year of service.
4. Smart Voltage & Dry-Run Protection
The system includes built-in safeguards against over-voltage, under-voltage, and over-current. When paired with the included float switch, the pump automatically detects when your source is low or your tank is full, preventing the motor from “dry-running” and extending its functional life.
5. Passive Cooling & Ceramic Bearings
To withstand the friction of deep-well pumping, SHIYUAN uses ceramic carbon thrust bearings. These high-grade bearings are water-lubricated and dissipate heat effectively, ensuring the pump can run for extended hours under the intense tropical sun.
Primary Applications
