The video, starring Rubén, is a detailed technical narration about the complex installation and startup of a water pumping system in an irrigation project on a remote island off the mainland. Rubén, an experienced pump systems engineer, faces a considerable technical challenge when he receives a concerning call from the client, informing him that the water does not reach the required height of 180 meters.

To bring water to great heights, Rubén explains that multistage pumps and pumping in stages are required. In this case, two stations with powerful 60hp multistage vertical pumps are used, which must raise the water to a total height of 360 meters. However, a problem arises at station 1, since the first pump fails to reach the pressure necessary to raise the water up to the desired 180 meters.

The installation presents complex technical specifications, such as a flow rate of 14 LPS and a pressure of 190 mca for the first pump. The system is powered by an electric generator and a variable frequency drive, which adds a layer of complexity to the pump control.

Rubén describes the detailed procedure for starting and starting the pumps, including the visual inspection of the installation, the disconnection of power sources, the closing of the discharge valve and the proper priming of the pump. In addition, it highlights the importance of verifying the direction of rotation of the motor in threephase centrifugal pumps.

When encountering the problem with a lower head than declared, Rubén uses the pump manufacturer's technical manual, which provides a table of problems and possible causes with their respective solutions. Rubén is ruling out possibilities until he identifies that the station 1 pump was rotating in the opposite direction, which affected its pumping capacity.

Subsequently, it faces the difficulty of massive leaks in the drive pipe, which affect the pumping flow. Rubén and his team carry out a meticulous journey to find and repair these leaks, thus ensuring that the flow is optimal and the water reaches the 180meter height necessary for irrigation.

Despite the challenges, Rubén is satisfied that he has successfully overcome the technical problems of the project and has achieved an adequate supply of water for farmers in the area. His experience and skills as a pump systems engineer have been instrumental in accurately resolving these challenging technical aspects of the project.
