Grundfos 16SQF10 SQFlex Solar Submersible Well Pump

Grundfos 16SQF10 SQFlex: The Highest-Flow Solar Pump in the Range

The Grundfos 16SQF10 is a high-capacity member of the SQFlex family, delivering up to 16 GPM for large-scale off-grid water supply applications powered by solar, wind, or hybrid AC/DC energy systems. Designed to operate across a wide input range of 30V to 300V DC or 90V to 240V AC, the 16SQF10 harnesses the variable output of renewable energy sources directly — eliminating the need for batteries or inverters in many installations and dramatically reducing system complexity and cost. With its robust flow rate and broad voltage compatibility, it is an ideal solution for high-demand agricultural operations, large off-grid homesteads, livestock watering systems, and community water supply projects where consistent, high-volume water delivery is non-negotiable.

Built to the same exacting standards as the rest of the SQFlex lineup, the 16SQF10 features a fully stainless steel motor and pump housing engineered to handle sand-laden water, aggressive water chemistry, and the temperature fluctuations inherent in deep well environments. The variable-speed motor automatically modulates pump output in real time to match available power, maximizing energy harvest from solar arrays and wind turbines across all lighting and weather conditions. The integrated Grundfos CU 200 control unit provides intelligent protection against dry-running, overload, and electrical faults — safeguarding the pump in remote installations where service calls are costly and inconvenient.
