Features

Economic and powerful, high efficient

Compact design, easy installation

No plumb exudation, more safe

Can sustain continual heavy duty work

Low or no maintenance

Whisper quiet operation

Various protection functions

DC power supply or battery is applicable

Billowy flow rate 20LPM at 24V DC is available

Motor

DC brushless motor with energy efficiency technology use MPPT by micro processor, and variable speed & power consumption optional by dial control.Stable & advanced soft-starting function, very low

in-rush current, perfect for working directly with PV panel

Impeller

Highly efficient and dynamically balanced with fine ceramic bearing for smooth ultra quiet operation.

Construction

Wetted parts are food grade stainless steel, food grade thermoplastic (Viton), carbon and ceramic for superior reliability and corrosion resistance.

Dry-running protection

Drive circuitry can detect no or little liquid in pump chamber and will stop the pump to prevent damage,pump is then restarted manually by disconnecting and reconnecting it to the power supply .

Over voltage protection

When the voltage over 28V, the pump will auto-protect and shut off own power supply, when the voltage falls below 28V, the pump will restart automatically.

Over load protection function

This means that when the current is over the rated current, such as can arise if the impeller is stuck due to debris. The pump will automatically stop to prevent damage, and will restart when the current falls again.
