Product Features
█ Dual Outlet Design (Horizontal/Vertical)
Adapts to different installation space requirements and is user-friendly.
█ Ultra Quiet
By replacing traditional fan designs, operational noise is greatly reduced. Moreover, the centrifugal impeller design significantly reduces operating noise, achieving a quietness comparable to a library at just 48 dB(A).
█ Lifespan Extension
Water-cooled reduces operational temperature and wear, extending the motor's lifespan and providing stable, long-term service for users.
█ Drainage Hole Design
To prevent water from directly entering and damaging the motor when the mechanical seal wears out.
█ Energy Efficiency
Superior to traditional air cooling, Water-cooled significantly reduces heat generation and loss, enhancing energy savings for users.
█ Quality of Water Usage
Wet parts are constructed from top-quality corrosion-resistant materials.
█ Antimicrobial
The only global brand to offer water pumps with Ag+ ions in the casing, SGS-certified to effectively prevent bacterial growth.
█ Thermal Overload protection
Equip with a thermal overload protection device to prevent motor burnout.
█ 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.
█ Anti-cycling function
To avoid frequent pump start-stop problems caused by low water flow.
█ All-in-one unit
Integrates the pump, motor, pressure tank, electronic control board, and pressure switch to deliver a stabilized water supply.
