4DLRAD4DLR7.5-110-150-1500-A/D Series Solar Deep Well Pumps:

Key Features and Highlights

Seamless AC/DC Hybrid System: The AD version is flexibly designed to use both solar (DC) and AC/generator power simultaneously. This ensures your water supply is uninterrupted around the clockutilize free solar power during the day and switch to AC power at night or during prolonged cloudy periods.

Intelligent Dual-Mode MPPT Controller: Our advanced hybrid controller employs high-precision MPPT technology. It prioritizes solar power to minimize electricity costs and automatically manages power input, maintaining optimal pump performance and motor stability under any power source.

Real-Time Performance Dashboard: Equipped with a high-definition LED interface, it clearly displays system operation. Real-time monitoring of critical data such as speed makes system management and troubleshooting easier than ever before.

Precision Low-Flow and High-Head Efficiency: The DLR series is meticulously engineered for specialized high-pressure applications. Ideal for precision industrial boosting, long-distance uphill water transport, or high-head pressure maintenance, it delivers a focused, consistent flow rate with exceptional lift capability. This ensures stable, high-pressure performance even in the most demanding vertical or long-range delivery environments.

Rugged and Durable Stainless Steel Construction: Utilizing a premium stainless steel casing and corrosion-resistant internal components, it is designed for long-term durability. This industrial-grade durability ensures the pumps can withstand the most demanding downhole environments with minimal maintenance requirements.

Professional 2-Year Warranty and Engineering Support: We offer a comprehensive 2-year warranty on our products. Our professional technical team will provide expert guidance on system selection and installation to ensure the long-term success of your projec
