Grundfos SQFlex Solar & Wind Powered Submersible Pump System
The Grundfos SQFlex combines state-of-the-art pump technology with sustainable, energy-efficient solutions to provide reliable water supply to remote locations with little or no access to water and electricity. Based on renewable energy sources such as solar and wind power, SQFlex adapts to the characteristic weather profile of any location, transforming areas that would previously have been considered uninhabitable into viable and attractive environments for people, livestock, and agriculture. Human existence and business prosperity in remote locations depend largely on clean water availability—SQFlex lends nature a helping hand by providing both water and the power needed to fuel the pump system.
As an authorized Grundfos Water Pump Dealer in Dubai, we supply the complete SQFlex range with genuine warranty and technical support across the UAE and Middle East region.
