CRFlex

Overview

Overview

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.

With variable speed operation and motor protection built in as standard, Grundfos solar surface pumps offer

  • Easy installation
  • Virtually no maintenance
  • Low cost and highly-efficient pumping

Applications

The Grundfos solar surface pump system is designed for renewable energy supply. Powered by a solar panel, the system is especially suitable for supplying water in applications such as these:

  • irrigation
  • livestock
  • pressure boosting

      - Water supply for cabins or off-grid homes

The MGFlex motor can be mounted on select Grundfos CR pump models.

Features and benefits

Maximum Power Point Tracking (MPPT)
The motor continuously optimizes the speed according to the input power available when connected to DC supply.

Wide voltage range
The wide voltage range enables the motor to operate at any voltage from 110 to 415 VDC or 220 to 240 VAC.

The motor will operate from 100 VAC with a derated power (at maximum input current 3 Arms).

Overvoltage and undervoltage protection
Overvoltage and undervoltage may occur in case of unstable power supply or a faulty installation.

The motor will be cut out if the voltage falls outside the permissible voltage range, and it will be cut in when the voltage is again within the permissible voltage range. No extra protection relay is required.

Overload protection
The motor is supplied with built-in thermal protection according to IEC60034-11, both steady overload and stalled condition. It will be stopped and restarted automatically.
