Stable water supply: The design of the centrifugal impeller generates a constant water pressure, which ensures a constant supply to the sprinkler arms. Minimal pressure fluctuations during cleaning maintain stable performance. DURABLE LEAKPROOF DESIGN - Fully sealed and waterproof motor and mechanical shaft seal support long time operation in high temperature and humidity environments. Effectively prevent water leakage, thereby extending the life of the unit. Quiet Operation: Precision dynamic balance impeller and damped mounting base keep operating noise below 50 decibels. Cleanliness will not disturb family rest. Wide Voltage Adaptability: Support 180-250V input voltage, adapting to regional power grid conditions. It continues to operate normally during voltage fluctuations, thus protecting internal components.
