PRODUCT INFORMATION
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.
Suitable for:
- Controls & Digital Groundwater Management
- Solar water solutions
- Solar Controls & Digital Water Management
- Solar Water Treatment Fertigation & Dosing
- Community water supply
Vertical multistage pumps with Renewable MGFlex motor for solar, wind and AC powersource. Runs on both AC and DC voltage
