Center pivot irrigation systems require to be installed in areas with abundant surface water sources, and to count on reliable irrigation pump systems capable of operating with limited water availability. In context where such requirements are not able to be met, the implementation of a floating solution, such as Todaro, ensures a stable and reliable pumping performance.
To address the issue of insufficient water resources, artificial reservoirs are built by excavating the ground around the pit and laying the foil and then filled from wells drilled nearby or by natural rainfall. Thus, the pond gains height and the suction depth can go over 6 m, making it difficult for standard centrifugal pumps to guarantee efficient operativity. Consequently, technical performance is additionally complicated by the need for an automatic vacuum so that the pump is filled with water.
Engineered to meet the need for simultaneous pumping and filtration, Todaro guarantees operational continuity and high system reliability even in conditions with challenging suction depth, insufficient yield from existing wells and variable water availability, representing the ideal solution for issues like the one encountered in the field.
Benefiting from its floating configuration, the application of the Todaro unit allows the system to overcome the aforementioned issues related to suction depth. Composed of a horizontal submersible pump integrated with the Riverscreen Gravity 12” rotating filtration system, Todaro ensures reliable operation by preventing these limitations, provided that a 36-mesh screen is installed; this configuration enables more effective filtration, ensuring complete exclusion of debris at the inlet of the center-pivot machine, while avoiding pressure losses with the filtration performed directly at source level.
as the constant flooding of the pump allowed by the floating configuration removes the need for vacuum-assisted priming systems.
In conclusion, the Todaro unit proved to be the ideal solution for this application, delivering key operational advantages: continuous pump rediness ensured by submerged operation, source-level filtration with no additional pressure losses, simplified installation with consequently reduced commissioning time, and high operational flexibility, including multi-unit parallel configurations for increased capacity.
The system can also be integrated with auxiliary solutions such as the Lampo unit, which provides electrical power to the center pivot irrigation system, enabling a fully autonomous and hydraulically protected setup suitable for off-grid or remote agricultural applications.
The overall configuration ensures a robust, scalable, and efficient pumping solution, capable of maintaining high performance even in irrigation scenarios characterized by limited water availability and demanding hydraulic conditions.
