Modelo: SQFlex 0,6-3- Sku: GRUNBOM001
- Vendor: Grundfos
Specifications
Product Description
The Grundfos SQFlex 0.6-3 Solar Pump is a 3" submersible pump with a helical rotor designed to deliver water to great heights with moderate flow rates, reaching up to 200 m and 1.3 m³/h. Its MPPT electronics allow it to operate directly with solar energy in DC or with single-phase AC power supply, offering a hybrid, robust (IP68), and extremely efficient solution for deep wells, tanks, and remote water supplies.
Main Features
- Pump diameter: 3" (installable in wells from Ø 76 mm).
- Maximum head: 200 m; maximum flow: 1.3 m³/h.
- Input power (P1): 1.4 kW with integrated MPPT management.
- DC electrical range: 30–300 Vdc; single-phase AC: 90–240 Vac, 50/60 Hz.
- Construction in AISI 304 stainless steel, protection rating IP68.
- Hydraulic outlet Rp 1 1/4" with integrated non-return valve.
Advantages or Benefits
- True AC/DC hybrid: operates with photovoltaic only, grid/generator only, or by combining sources, without external inverters.
- Stable performance with variable irradiation thanks to MPPT, maximizing water production throughout the day.
- Protection against dry running and probe management via controller, extending equipment lifespan.
- Helical (progressive cavity) design optimized for high heads with contained consumption.
- Simple installation and maintenance with a wide range of accessories and automation.
Purpose or Applications
Especially suitable for solar pumping in deep wells for agricultural and livestock operations, supply to isolated homes, filling elevated tanks, hillside drip irrigation, and long column water transfers. Also suitable for operation with generator or grid in mixed or backup scenarios.
