【Function】 Equipped with an integrated, highly sensitive sensor, the system automatically detects changes in water level, enabling intelligent starting and stopping of the water pump. When the water level is low, it automatically shuts off the power supply, effectively preventing dry running and ensuring device safety – all while maintaining high efficiency and energy savings 【Wide Applications】 Compatible with various pump types, including self-priming pumps, jet pumps, centrifugal pumps, garden pumps, and fresh water pumps. Widely used in domestic water supply, irrigation systems, pressure boosting systems, and other applications to meet diverse water needs 【Function】 By eliminating pressure tanks, check valves, and complex piping, the integrated one-button design significantly simplifies water pump control. It saves space and installation costs and allows for easy upgrades – the ideal replacement for traditional pressure switches 【Suitable For】 Suitable for clean, particle-free water environments, ensuring long-term stable operation of the internal components. Prevents malfunctions caused by water quality problems, extends service life, and guarantees continuous and efficient system operation 【High Quality】Made of high-strength engineering plastics and corrosion-resistant metal components, it features a robust construction and excellent sealing. Rigorous pre-delivery testing confirms its superior water and dust resistance. Even after years of use, it does not age, ensuring reliable quality, Weight: 2.69845808688 Pounds, Manufacturer: Kuuleyn
