Efficient management of groundwater resources is a critical challenge for agricultural production, particularly in arid and semi-arid regions where irrigation systems depend on reliable water supply. This study presents a resource- and energy-efficient technology for tubeless water lifting from wells using a submersible electric pump equipped with a novel hydraulic packer device with an ejector. The research aims to improve the performance of groundwater extraction systems for agricultural water management by reducing energy consumption, simplifying installation, and increasing operational reliability. A comparative analysis of conventional pipe-based water lifting systems and the proposed tubeless technology was conducted, supported by theoretical modeling and laboratory experiments. The results demonstrate that the proposed system reduces metal consumption by 1.5-1.7 times, decreases energy consumption by up to 20%, and increases pumping unit efficiency and discharge by approximately 20%. The use of an ejector enhances water intake under varying hydrogeological conditions and improves the performance of low-yield wells. The findings indicate that the developed technology can significantly enhance the efficiency and sustainability of groundwater use in irrigation and agricultural water supply systems. The proposed solution is particularly suitable for decentralized water supply in rural and pasture-based farming systems in water-scarce regions.
