Floatation system shall be individual modular pontoons constructed of commercial grade marine dock float drums. Drums shall be filled with expanded polystyrene and fully sheathed with UV inhibited polyethylene. The drums shall be securely bolted to a fabricated galvanized structural steel framework. Float system shall consist of matched pairs of pontoon and framework assemblies. Float system shall be sized so that fully weighted water line is no more than 70% of pontoon height.

The fabricated steel pontoon framework shall allow the pump to pivot from a horizontal position parallel to the water surface to the vertical running position. Pivot assembly shall provide for locking the pump in the vertical running position with hardened steel pins. A frame mounted winch assembly shall be provided for lifting the intake end of pump assembly up out of the water for launch, inspection while in position, and recovery. The pivoting pump/ motor mount shall incorporate a mounting positioning feature for adjustment of the volute/ impeller submergence for proper performance. A crossover bracing frame spanning between the pontoon halves shall be included and fitted with a lifting point capable of supporting the entire unit’s assembled weight. The receiver-cradle for the pump body pivot arms on the pontoon framework shall allow for installation and removal of the pump assembly without separation of the pontoon framework. Accessory support skids to allow for the pump settling to the bottom of the pond preventing the pump intake becoming mired shall be an integrated design option supplied by the Manufacturer.

The pump intake shall be protected with an appropriately sized intake suction screen to protect the pump from fish and debris while maintaining adequate flow to the pump under normal operating conditions. Accessory hydro-mechanical strainers may be substituted as optional equipment as required.

All motors shall meet as minimum requirements the published standard rules and regulations of NEMA, ANSI, and IEEE with respect to manufacture and test.

Variations and exceptions from the above specifications will be considered provided the bidder calls particular attention to such exceptions and explain in detail the reasons and advantages for the exceptions.
