SHIYUAN 20M Solar Submersible Pump: High-Efficiency Water Solutions for Off-Grid Living
Unlock a reliable and sustainable water supply with the SHIYUAN 20M Solar Submersible Pump. Specifically engineered for shallow wells, boreholes, and water transfer applications, this 12V DC-powered pump is the ultimate solution for regions without access to grid electricity. With a 20-meter maximum head (lift) and a robust flow rate, it is designed to meet the daily water demands of small-scale farms, livestock, and residential households.
Built with premium materials and advanced BLDC (Brushless DC) motor technology, the SHIYUAN 20M series offers unmatched durability and energy efficiency. By running directly on solar power, this pump eliminates monthly electricity bills and the need for expensive diesel generators, providing a rapid return on investment and a cleaner, greener environment.
The SHIYUAN Engineering Advantage
The SHIYUAN 20M pump stands out due to its precision-crafted internal components:
-
Laser-Welded Impellers: Unlike plastic alternatives, these high-strength impellers provide superior pressure and are resistant to wear from sand and silt.
-
100% Stainless Steel Body: The AISI304 stainless steel casing offers maximum protection against corrosion and rust, even when submerged for years.
-
Brushless DC (BLDC) Motor: Extremely efficient and low-maintenance, the motor utilizes rare-earth magnets to deliver high torque and consistent performance.
-
Integrated Strainer: Features a built-in stainless steel strainer to filter out debris and protect the internal motor from sandy water.

Product Highlights
1. Optimized for 12V Solar Systems
This pump is specifically designed to integrate seamlessly with standard 12V solar power setups. It can be powered directly by a 250W–300W solar panel, making it an incredibly easy and cost-effective system to deploy in rural or remote areas where 24V or 48V systems might be over-budget.
2. Superior Lift & Pressure
With a 20-meter vertical lift, the SHIYUAN pump is perfect for drawing water from shallow wells or pushing water from a surface source (like a river or dam) up to an elevated storage tank. It ensures that even at height, you maintain a steady, reliable flow of water for your taps and irrigation lines.
3. Maintenance-Free Ceramic Bearings
To ensure a long service life, the pump utilizes ceramic carbon thrust bearings and encapsulated windings. These high-grade materials significantly reduce friction and heat buildup, allowing the pump to operate for extended hours under the hot tropical sun without risk of overheating.
4. Easy “Plug & Play” Installation
The SHIYUAN 20M is designed for simplicity. It comes with a 20-meter submersible cable already attached, allowing for quick deployment. Its compact 3-inch diameter means it can be lowered into most narrow boreholes or placed inside a standard water tank with ease.
5. Safe & Smart Operation
Equipped with safety features to protect against voltage fluctuations, the pump ensures that your motor remains safe during the varying light levels of the day. When paired with a float switch, the system can automatically shut off when your tank is full, saving both water and energy.
