Product Introduction
The 4" DC built-In plastic impeller solar pump is a submersible deep-well pump with a diameter of approximately 96 mm, specifically designed for off-grid water supply applications requiring higher flow rates and greater efficiency. Compared to the 3-inch model, it features significantly expanded specifications in terms of power range, flow rate, and head, making it capable of meeting the demands of medium-scale farm irrigation, centralized water supply projects, and commercial water usage.

FAQ
Should my water pump have a plastic or metal impeller?
The choice between a plastic or metal impeller depends primarily on your water quality conditions and specific operating environment.
Plastic impellers offer the advantages of being lightweight, corrosion-resistant, and cost-effective. They typically deliver excellent performance in clean-water applications, such as residential water supply, garden irrigation, or low-pressure systems.
In contrast, metal impellers boast significantly greater durability and wear resistance, making them the ideal choice for pumping water containing sand, silt, or other harsh impurities.
