Abstract: The disclosure describes the improvement of mobile floating submersible pump systems where such systems are used for rapid deployment water transfer. Such systems are deployed within industrial fire fighting, flood control operations (FIG. 7) and similar water transfer requirements. A floating submersible pump is designed to separate the power system (FIG. 7, item 11), such as a diesel engine, from the pump body (FIG. 7, item 16), which further enables the operator to deploy a pumping system where traditional ground based centrifugal pumps are unable to physically siphon the water. Floating submersible pump systems are cumbersome in nature, requiring heavy equipment and significant manpower to deploy them. The innovation disclosed uses advancements in structural fiber reinforced materials to drastically reduce the weight of such systems, which removes the need for heavy deployment equipment, with the added benefit of corrosion protection from saline environments through the use of chemically inert composites.
