Features

Inverter controller
The motor starts smoothly during water usage, with the inverter controller continuously adjusting the motor speed via pressure sensor feedback to maintain stable pressure at the preset value.
Smart and Energy-Saving
The pump will maintain a constant operating pressure at the pressure setting, ensuring a stable water supply even though occasionally the output flow is over the capacity.
Dry-Run Protection
Auto shutoff after 1 minute of dry run; restarts hourly until water is restored.
Auto Stop Upon Flow Interruption
The pump will automatically cycle down as water usage decreases
Pressure Compensation
Automatically detects pressure loss and operates the pump to maintain the pressure setting if there is leakage or dripping in the piping system.
Antibacterial
The first and only pump in the world with antibacterial properties, incorporating Ag+ silver ions, certified by SGS to effectively inhibit the growth of certain bacteria.
Quiet and Durable
The impeller is made of SUS304 stainless steel to ensure quite operation, high water quality and strength.
All-In-One
Integrated system that combines the pump, Inverter, motor, pressure tank, and electronic controller for a stable and enduring water supply environment for household use.
