Features

Outstanding Exhaust Performance
An optimized structure combined with gear impellers self-regulates the pressure differential, enabling rapid water return and quick air removal to prevent supply disruption caused by air blockage.
Power Module
Equipped with industrial-grade safety protections, it adapts to various voltage conditions to ensure consistently stable water pressure.
Thermal Overload Protection
The motor is equipped with a temperature overload protection device, effectively preventing motor damage due to overheating for reliable safety.
Double Dry-Running Protection
Features a built-in temperature protection switch and a dry-running protection device to prevent overheating caused by operation without water, ensuring safe use.
Rapid Cycling Protection
A design allows for programmable control to delay shutdown by 6 seconds, avoiding frequent pump starts and stops due to low water volume, effectively extending the pump's lifespan.
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.
Rust-Resistant
The parts in contact with liquid are made of rust-resistant materials, ensuring water hygiene at the source and protecting your family.
