SDJ Solar Agriculture Water Pump

SDJ solar agriculture water pump is developed based on China's SDJ 231—87 "Terms for Pumping Station, Well, Sprinkler Irrigation and Drip Irrigation Projects" , addressing the core pain points of water conservancy and agricultural projects: strict standard compliance requirements, unstable power supply in rural areas, and harsh working conditions (corrosive water, sand-containing sources). As a versatile addition to our pump lineup, it bridges the gap between small-scale SQB surface pumps and large-scale SSC deep well pumps—covering medium to large agricultural and municipal needs with balanced performance and cost-effectiveness. Equipped with a DC permanent magnet brushless motor (efficiency ≥90%) and integrated MPPT controller, the SDJ pump operates on solar power during daylight (zero energy cost) and automatically switches to AC power (110V/220V/380V) for 24/7 uninterrupted use . Its "water storage instead of power storage" design eliminates battery replacement costs and environmental pollution—ideal for remote areas with no grid access . The full 304 stainless steel construction (pump body, impeller, shaft) avoids the common issue of shaft breakage in traditional pumps and resists corrosion from agricultural chemicals, mild saltwater, and sand-containing water (sand content ≤3‰) .

Product Introduction

Our SDJ Series AC/DC Solar Water Pump is a professional water-extraction solution engineered for agricultural irrigation, water conservancy projects, deep well ,and landscape water features. Compliant with China's water conservancy industry standard SDJ 231-87, it integrates AC/DC auto-switch technology, high-efficiency BLDC permanent magnet motor, 99% efficiency MPPT controller, and full 304 stainless steel structure-operating seamlessly on solar energy (daytime) or grid power (night/cloudy days) without batteries. With a power range of 0.75kW-15kW, max lift up to 325m, and flow rate 4.5-130m³/h, it adapts to diverse scenarios: 0.5-500 acre farms, rural community water supply, deep boreholes, and municipal sprinkler systems. Crafted with 304 stainless steel (avoids shaft break risk) and IP65 waterproof protection, it complies with CE, EN 60335-2-41, and EN 62253 standards-trusted by users in Southeast Asia, Africa, the Middle East, and South America for its durability and compliance.
