e descrizione del Product name
prodotto The Grundfos CR Flex is a multi-stage centrifugal, in-line, non-self priming surface pump specifically designed
for water transfer, irrigation and pressure boosting in solar-powered applications. It is fitted with the advanced
MG Flex variable frequency driven motor that offers the following features:
• Runs at varying speeds depending upon the energy input available. Product
• Can be used for DC or AC power supply and can therefore be connected to either PV solar modules, a
standby AC generator or mains power supply as required.
• Built in protection for under and over voltage and system overload. No additional protection is therefore image
required.
• One set of terminals is included for either high or low-level control functions.
4 Multiple models are available, all powered by the same 1250 W motor providing a selection of head and flow Grundfos solar surface pump
