Stable and abundant water power: The internal structure is optimally designed, delivering uniform and stable water power output, with a continuous flow. It can meet cleaning operation needs, with moderate water pressure, better cleaning efficiency, and a smooth user experience. Tightly sealed to prevent leakage: Multiple sealing structures are used, with interfaces and cavities tightly closed, making it unlikely to leak or drip during operation. It can remain dry even after long periods of continuous work, preventing water from affecting other parts of the machine. Low noise and vibration during operation: The dynamic balance process is precise, and internal components work accurately together, resulting in minimal vibration and soft noise during operation. It feels comfortable when handheld, without obvious noise, and does not disturb the surrounding environment during home cleaning. Compact and easy to assemble: The overall shape is small and neat, not taking up much space inside the vacuum cleaner. The hole positions and interface specifications are standard, making disassembly, maintenance, replacement, or installation very convenient. 12V Mini Vacuum Pump 8L/min High Pressure Suction Diaphragm Pumps with Holder, Manufacturer: liucaihong188
