Product Introduction
The 3" DC built-In plastic impeller solar pump is a submersible deep-well pump specifically designed for off-grid regions. With a diameter of just 3 inches (approximately 76 mm), it fits easily into standard deep wells. Powered by a core "photovoltaic conversion" mechanism, it currently stands as an economical and eco-friendly choice for agricultural irrigation, drinking water for humans and livestock, and garden water supply.

Features
• High-flow system for faster tank-fill and significant water output.
• Maximum Power Point Tracking (MPPT) for maximizing efficiency of input power.
• Soft-start feature prevents water hammer and increases system life.
• CE approved.
Advantage
• Built-in MPPT Controller
The pump body integrates a Maximum Power Point Tracking (MPPT) controller, capable of tracking the solar panels' peak power in real-time to enhance power generation efficiency and stability.
• High-Efficiency Motor
It utilizes a permanent magnet brushless DC synchronous motor, offering a 15% to 30% increase in efficiency compared to standard motors, along with quieter operation and a longer service life.
• Plastic Impeller and Key Materials
The fluid-contacting components are constructed from high-strength engineering plastics, combining excellent wear resistance with lightweight characteristics. The pump casing and critical components are typically made of AISI 304 stainless steel, ensuring exceptional durability.
Application Scenarios
FAQ
Routine maintenance of the 3" DC Built-In Plastic Impeller Solar Pump
3-inch DC solar pumps featuring internal plastic impellers are generally low-maintenance products; however, regular inspection and cleaning can significantly extend their service life.
• Controller and Motor Maintenance: Regularly clean the heat sink fins; inspect wiring terminals; and perform insulation resistance testing.
• Hydraulic Components and Impeller Maintenance: Inspect the plastic impeller for wear; check the integrity of the check valve seal; and perform periodic flushing.
• System Operating Environment and Troubleshooting: Ensure that the open-circuit voltage of the solar panel array does not exceed the controller's permissible range; conduct dry-run protection tests, etc.
