Grundfos
SQ Flex
The Grundfos SQ Flex pumping systems are a giant leap forward for solar water pumping. Grundfos, the worlds largest pump manufacturer, has reduced the cost of the pumps along with reducing the power needs. The result is a Grundfos centrifugal or helical rotor quality system for about the cost of a diaphragm pump. The Grundfos SQ Flex pumping system can also be powered by a wind generator if you have the right site. The Whisper WHI-200 Waterpumper on page 53 is the required generator.
CU 200 Control Unit A user-friendly interface box that maintains two-way communication with the pump and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status power consumption and level switch input.
IO 100 Switch Box A very simple and easy-to-use system with cable interface. Controlled by a manual on/off switch.
IO 101 Switch Box Acts as interface for powering back-up supplies, providing automatic change-over. For instance when changing from generator to solar energy, the solar panels automatically power the system as soon as the fuel tank runs dry.
Level Switch Save energy as you save water. With a level switch inside the storage tank connected to the CU 200 control unit, the pump knows when the tank is full and shuts itself off
Features:
Up to 390 foot head applications
30-300 Vdc, or 90-240 Vac single-phase AC input.
Permanent magnet high efficiency motor
Overload protection
Over temperature protection
Dry running protection
Maximum Power Point Tracking to optimize pump operation according to DC Power available.
Power line communication with the CU200 (optional) to display operational conditions
