Caprari has been installing inclined submersible pumps on riverbeds, lakes and artificial basins for many years. The pumped water is primarily used for irrigation. However, the water is also used for flood control or water supply in general. This type of installation has also been used for other applications where system and environmental requirements were similar to those above, such as mines and industrial plants, etc.
Inclined submersible pumps can offer advantages compared to vertical or horizontal pumps mounted on floating platforms, particularly because they can be installed easily. Inclined on the bank of the basin, the submersible pumps do not require the installation of large structural parts.
Highly compact Because the pumps are highly compact machines they can be positioned on banks with very irregular slopes with no need for the shaft to be aligned. The pumps are handled easily, the bearings are less stressed and the level of noise generated by these pumps is low.
There is wide range of wet ends and submersible motors to choose from. Caprari’s know-how aims to assure total reliability and efficiency in the product’s selection and installation, with guarantee of a long operating life of the system as demonstrated by the dozens of projects installed around the world.
For example, in the municipality of Zamora, Spain, the solution called for a special wheeled system, designed to set the pump to avoid vibrations and then insert it inside the pipe. Initially, the pumps remain in a horizontal position thanks to the application of several floats, but when the water level lowers, the pipe as well as the built-in pump get inclined.
