The Future of Urban Water Systems As urbanization accelerates globally, urban water supply systems are facing challenges. Population growth, industrial development and environmental changes have all placed higher demands on urban water supply systems. Against this background, the emergence and popularization of the Self-Priming Jet Pump (https://www.wertome.com/product/self-priming-jet-pump/selfpriming-jet-pump/)is of great significance for the future development of urban water supply systems. The high efficiency of Self-Priming Jet Pump brings significant energy saving effect to urban water supply system. Conventional pumps need to be filled before starting, a process that is both time-consuming and energy-consuming. The Self-Priming Jet Pump, on the other hand, through its unique design, automatically extracts and removes air from the pump prior to startup, allowing for rapid filling.
