The Grundfos 11SQF-2 SQFlex is a versatile, high-performance submersible pump designed to deliver dependable water flow in both on-grid and off-grid applications. It runs on AC or DC power, so it pairs with solar arrays, battery banks, generators, or traditional electrical service, making it an ideal solution for remote homes, cabins, farms, and livestock operations. It delivers up to 13 GPM and lifts water from depths up to 395 feet.
Built with the durability the SQFlex line is known for, the 11SQF-2 uses corrosion-resistant materials, protection against dry-running and voltage fluctuations, and smooth, efficient operation with minimal maintenance. Whether it is your primary water source or part of a solar pumping system, it adapts to changing energy needs without compromising output.
The SQFlex motor accepts 90-240 V AC or 30-300 V DC, so the same pump runs on grid power, a solar array, a battery bank, or a generator without swapping equipment.
Wide DC input and a power factor of 1.0 make it a natural fit for off-grid water: remote homes, cabins, farms, and livestock operations where grid power is not an option.
Delivers up to 13 GPM and lifts water from depths up to 395 feet, so deep wells still get consistent, usable flow.
Protection against dry-running and voltage fluctuations helps prevent motor damage when well levels or power quality change.
Built with corrosion-resistant materials for long-term durability in harsh well environments, with minimal maintenance requirements.
At 18.1 lb with a slim 3-inch body, it installs easily in narrow well casings where larger pumps will not fit.
