Description
CRFlex for remote water delivery systems
The Grundfos CRFlex in-line multi-stage solar surface pump is designed for renewable energy supply and can operate in remote areas lacking mains electricity. Powered by a solar panel, the system is especially suitable for supplying water in applications such as the watering of livestock, pressure boosting and irrigation.
The CRFlex solar surface pump comes with the MGFlex motor. We can deliver a complete solution including solar panels, IO 50 switch box, level switch for the water reservoir, water pipe, non-return valve and optional dry-running switch. This solution offers the benefits of easy installation, maintenance confined to periodic cleaning of the solar panels and a few, simple components.
The difference is in the MGFlex motor
The MGFlex motor is optimised for converting photovoltaic DC power to AC, producing output identical to a standard variable frequency drive, and also works with other Grundfos pumps.
Maximum power 24/7
Maximum power point tracking (MMPT) monitors the pump’s own power generation several times per second and makes sure it runs at maximum at all times.
The best solution
No energy use from a renewable source, ensuring a cost-effective, flexible and secure water supply solution.
Automatic operation
Built-in motor protection against overload and low voltage ensures that the pump operates in a wide voltage range.
