Specifications
Product Description
The Grundfos SQFlex 3A-10 Solar Pump is a professional solution for water supply in medium wells and solar irrigation. It combines a hybrid motor capable of operating on both alternating and direct current with integrated MPPT, offering high performance with optimized consumption. Its 4" centrifugal hydraulics reach up to 70 m head and 5 m³/h flow rate, with AISI 304 stainless steel construction and IP68 submersible protection for long service life in demanding environments.
Main Features
- 4" centrifugal hydraulics with up to 70 m head and 5 m³/h flow rate.
- Hybrid AC/DC motor 1×90–240 V AC and 30–300 V DC with integrated MPPT to maximize solar energy.
- Input power P1 of 1.4 kW and nominal speed of 3600 rpm; direct start.
- Protection rating IP68 and insulation class F; integrated check valve.
- Body, impellers, and rotor in AISI 304 stainless steel; corrosion-resistant design.
- Electronic protections: dry running, over/under voltage, and overload.
Advantages or Benefits
- Energy efficiency: the internal MPPT adjusts the operating point to extract the maximum from the PV panels.
- Total flexibility: operates with solar panels, generator, grid, or wind systems.
- Reliability IP68 submersible and stainless materials that reduce maintenance and downtime.
- Simple installation: no external inverter; Rp 1 1/4" outlet and minimum well diameter 102 mm.
- Service continuity: intelligent protections and check valve that prevent water hammer and dry running damage.
Purpose or Applications
Designed for pumping in standard diameter cased wells, storage tanks, drip or sprinkler irrigation on farms, livestock, and rural supply. Its hybrid motor allows combining solar energy with grid or generator to ensure flow on cloudy days or during peak demand.
