T y 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 stand-

ard, Grundfos solar surface pumps offer
