Key Points for Selection, Installation, and Maintenance of DC Submersible Pumps

Selection criteria: Choose a pump with a rated head that equals the actual required head plus pipeline losses (10%–15%). Match the flow rate to the water demand. If the liquid contains particles or is corrosive, select materials that are wear-resistant and corrosion-proof (e.g., 316 stainless steel or engineering plastics). For solar-powered applications, prioritize BLDC motors paired with MPPT controllers.
Installation: Absolutely no dry-running without water; do not pull on the cable; ensure the float switch is positioned accurately; ensure reliable grounding.
Maintenance: Regularly check for leaks in the seals; clean the inlet filter screen; avoid frequent starts and stops of the BLDC motor; when not in use for an extended period, store it in a dry place.
