Detailed Product Description of DC Stainless Steel Submersible Pump
I. Product Overview
This DC submersible pump is a dedicated water supply device for solar photovoltaic systems. The entire unit features a unibody stainless steel construction, allowing for complete submersion. It is compatible with 24V DC power supply, boasts a 250W high-power output, and requires no household AC power. Simply connect it to a solar panel for outdoor water extraction. It is widely used in outdoor scenarios without mains power, such as farmland irrigation, deep well water extraction, orchard water supply, RV water supply, and aquaculture water circulation. It comes with an extended waterproof power cord, is easy to install, and is quiet and durable.
II. Core Specifications
1. Power Supply Voltage: DC 24V
2. Rated Power: 250W
3. Operating Current: 8.0A
4. Outlet Diameter: 25mm standard interface, compatible with conventional water hoses
5. Power Supply Compatibility: Solar photovoltaic panel (250W photovoltaic panel indicated on the unit)
6. Operating Mode: Fully submerged underwater operation; no dry running allowed.
7. Unit Material: 304 stainless steel pump body shell, rust-proof and corrosion-resistant.
8. Accessories: Extended waterproof and tensile-resistant power cord, with waterproof insulation, preventing leakage underwater.
III. Unit Structure and Material Advantages
1. Stainless Steel Filter Shell: The pump body features elongated inlet filter holes to block sediment, aquatic plants, and large particles, protecting the internal impeller. The stainless steel material is resistant to slight acid and alkali corrosion from well water and river water, preventing rust even after long-term outdoor immersion and extending the overall lifespan of the unit.
2. Fully Sealed Waterproof Motor Cabin: The motor features a multi-layered waterproof sealing structure, preventing water leakage and short circuits even when submerged in deep water. It operates silently underwater, eliminating noise pollution.
3. High-Pressure Water Outlet Connector: An integrated top-mounted water outlet with a 25mm standard external thread ensures a secure connection to water pipes, preventing detachment and providing stable water pressure and ample head.
4. Extended Waterproof Cable: Equipped with a thickened black waterproof power cable. The insulation layer is wear-resistant and anti-aging, allowing for extension to connect to solar panels on shore. This facilitates long-distance water intake from deep wells and ponds.
5. Bottom Fixing Buckles: Metal fixing lugs on both sides of the unit allow for secure lowering into deep wells and reservoirs using ropes, ensuring stable installation and preventing tipping.
IV. Core Product Features and Highlights
1. Dedicated DC Solar Power, Independent of Mains Power: The 24V low-voltage DC design allows direct power supply from solar panels. It enables automatic water pumping in mountainous farmland, orchards, woodlands, and remote farms where 220V AC power is unavailable. Energy-saving and environmentally friendly, it operates with zero electricity costs. 2. Fully Submerged and Silent Water Extraction
The entire unit operates submerged in water, resulting in extremely low noise compared to surface-mounted self-priming pumps, minimizing disturbance to livestock and crops. Underwater cooling prevents the motor from overheating and burning out during continuous operation.
3. Rust-Resistant and Corrosion-Resistant, Suitable for Multiple Water Sources
The stainless steel pump body can draw well water, river water, spring water, and aquaculture pond water. It can also be used in water sources with slight sediment, as it is not prone to rust or clogging.
4. High-Flow and Stable Water Delivery
With a powerful 250W motor, the pump delivers ample water flow, meeting the needs of vegetable garden irrigation, fruit tree drip irrigation, aquaculture water changes, and domestic water intake. It also allows for long-distance water delivery.
5. Low-Voltage Safe Operation
Powered by 24V DC low-voltage electricity, even if the cable is damaged or submerged in water, there is no risk of electric shock, ensuring greater safety during outdoor water extraction operations.
V. Applicable Application Scenarios
1. Agricultural Planting: Solar irrigation and drip irrigation for orchards, vegetable gardens, and greenhouses;
2. Mountain Water Supply: Pumping water from deep wells, mountain springs, and ponds in rural areas;
3. Livestock Farming: Water exchange in fish ponds and automatic water supply for livestock drinking troughs;
4. Outdoor Living: Water supply for RVs, campsites, and photovoltaic courtyards;
5. Landscaping Projects: Watering of green seedlings and water circulation for small artificial mountains;
6. Remote Construction Sites: Temporary water supply for construction sites without mains power.
VI. Standard Installation and Usage Procedures
1. Securely connect the water hose to the 25mm outlet port at the top;
2. Thread the rope through the lifting lugs on both sides of the pump and slowly lower it into the well water/pool, ensuring the entire unit is completely submerged;
3. Extend the power cord to the shore and connect the positive and negative terminals to the 24V solar panel;
4. The solar panel generates electricity from sunlight, and the pump automatically starts pumping water;
5. After stopping the pump, disconnect the power supply first, then lift it out of the water to remove silt and sediment.
VII. Important Safety Warnings
1. Never run the pump dry: The pump must be completely submerged in water before being powered on. Running it dry will quickly burn out the motor.
2. Only pump clean water with low sediment levels. Do not pump sewage, mud, or corrosive chemical liquids.
3. Strictly distinguish between positive and negative terminals when wiring. Reversing the polarity will prevent the pump from working.
4. Regularly clean the water inlet of the pump to remove weeds and sediment to prevent insufficient water intake and motor overheating.
5. For long-term shutdown during winter, remove the pump, dry it, and store it to prevent freezing and cracking of the pump body.
6. Never pull on the power cord to drag the pump, as this may break the internal copper wires, damage the waterproof layer, and cause electrical leakage.
