Features

Engineered for Hot Water

Made from heat-resistant materials up to 90°C, ideal for solar hot water systems, offering pressure boosting at the system’s outlet.

Safe and Reliable

Equipped with a relief valve that automatically releases pressure when the pump system exceeds 5 kg/cm², ensuring safe operation.

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.

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.

Thermal Overload Protection

The motor is equipped with a temperature overload protection device, effectively preventing motor damage due to overheating for reliable safety.

Dry-Running Protection

Features program-controlled dry-run protection to avoid damage when the pump runs without water.

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.

Rust-Resistant

The parts in contact with liquid are made of rust-resistant materials, ensuring water hygiene at the source and protecting your family.

All-In-One

Integrated system that combines the pump, motor, pressure tank, and electronic controller for a stable and enduring water supply environment for household use.
