Grundfos SQFlex Submersible Pump (11 SQF-2)
Grundfos SQFlex submersible pumps are more than just pumps - they're complete water supply systems. With a built-in controller with MPPT and soft starting, plus the ability to run off DC or AC power without an external inverter, the Grundfos 11 SQF-2 pump's flexibility makes the perfect water supply solution in remote or off-grid areas where water is scarce and the power supply is non-existent or unreliable. A battery backup system can store the extra energy generated and take over when the primary energy source is not available.
The Grundfos 11 SQF-2 Submersible Pump is a helical rotor pump, ideal for situations where up to 280' of lift are needed. Its permanent magnet motor delivers flows of up to 13 gallons per minute and enables the efficient use of energy from a wide range of both DC and AC supply options. Fits 3" well casings.
