In solar pump projects, most people focus on pump power, flow rate and solar power supply conditions. However, changes in the water source itself also deserve attention. Especially for projects using groundwater, rivers or water tanks as water sources, the water level may be affected by seasons, rainfall and water extraction volume.

Exhibition Name: 18th Guangzhou International Solar Photovoltaic and Energy Storage Industry Expo
Date: September 16–18, 2026
Venue: Area B, China Import and Export Fair Complex, Guangzhou
Hall: Hall 10.2, 2/F, Area B
DIFFUL Booth: B451

Per the operating requirements for solar deep well pumps, the water quality shall be kept clean, with sand content controlled within 0.01% and pH value maintained between 6.5 and 8.5. Meanwhile, ferromagnetic impurities and solid particles shall be prevented from entering the pump body. If the actual water source contains excessive impurities, filter devices can be added according to site conditions.

As application scenarios for solar pumps keep expanding, solar pump dealers are faced with increasingly diverse customer demands. Even for agricultural irrigation or off-grid water supply projects, customers may have vastly different requirements for flow rate, head and installation methods. Therefore, for solar pump dealers, building a reasonable product portfolio matters more than promoting a single product type.

As the 2026 National Day holiday approaches, DIFFUL issues advance notice on production, order and shipment schedules during the holiday to all global customers and partners, helping you properly arrange procurement plans and project timelines.
