Grundfos SQFlex 5A-7 Solar Pump | 4" | 50 m | 7.5 m³/h | 1.4 kW

Product Description

The Grundfos SQFlex 5A-7 Solar Pump is designed to deliver high flow rates in irrigation and supply installations requiring up to 7.5 m³/h with heads up to 50 m. Its hybrid motor allows operation directly with photovoltaic panels or with grid/generator, integrating MPPT tracking to maximize available energy. Manufactured in AISI 304 stainless steel and with IP68 protection, it provides reliability, corrosion resistance, and a long service life in continuous operation.

Main Features

• High flow with low/medium head: up to 7.5 m³/h and 50 m manometric head.
• Hybrid AC/DC motor (1×90–240 V AC and 30–300 V DC) with integrated MPPT for maximum solar efficiency.
• Input power P1 of 1.4 kW, nominal speed 3,600 rpm, and direct start.
• Protection rating IP68, insulation class F, and electronic protection against dry running, over/under voltage, and overload.
• Construction in AISI 304 stainless steel for body, impellers, and rotor; integrated non-return valve.
• Hydraulic outlet Rp 1 1/2", minimum well diameter 102 mm, and 2 m power cable.

Advantages or Benefits

• Maximum efficiency: the internal MPPT adapts the operating point to actual irradiation, increasing daily flow with fewer panels.
• Total versatility: operates with photovoltaics, grid, or generator, switching without complex accessories.
• Lower maintenance: stainless steel hydraulics and electronic protections extend service life.
• Quick installation: compact 4" design, built-in non-return valve, and standard Rp 1 1/2" outlet.
• Service continuity: ability to operate under variable voltage conditions and protection against dry running.

Purpose or Applications

Ideal for drip or sprinkler irrigation on agricultural estates, filling tanks and livestock troughs, supplying rural homes, and water transfer in operations. Its high-flow profile makes it especially suitable for wells with good yield where moving large volumes of water with solar efficiency is a priority.
