Grundfos SQFlex Submersible Pump (3 SQF-3)
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 3 SQF-3 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 3 SQF-3 Submersible Pump is a helical rotor pump, ideal for situations where up to 655' of lift are needed. Its permanent magnet motor delivers flows of up to 3 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.
