Grundfos CRFlex

Grundfos solar surface pumps provide the perfect sustainable, reliable and cost efficient alternative to irregular water supply solutions in remote locations, or for highly specific applications anywhere. Theses pumps provide individual solutions to water problems where conventional water supply systems fail or simply cannot reach. Although the initial investment including solar panel is higher, the operating cost is minimal. Grundfos has developed the MGFlex motor for optimal performance using solar power, for surface pump applications. In addition to solar panels, Grundfos solar surface pumps can be run from the grid or a generator.

CRFlex Pump Features:

  • Maximum Power Point Tracking (MMPT) – Motor continuously optimizes the speed according to the input power available when connected to DC supply.
  • Wide voltage range – Operates at any voltage from 110 to 415 vdc or 220 to 240 VAC
  • Overvoltage and undervoltage protection
  • Overload protection
