0.75Kw 1.5m³ 120m Premier Brushless 3TG2-120-750W/72V 750W 1.0HP 1500L/h Borehole Submersible Water DC Pump (Screw Type)

The Premier Brushless 3TG2-120-750W/72V DC Borehole Submersible Water Pump is a deep-borehole solar screw pump built for very deep water lifting up to 120 meters where reliability and efficiency are critical. Driven by a 750W (0.75kW / 1.0HP) brushless DC motor, this pump delivers a consistent 1.5 m³/h (1500 L/h) flow, ideal for deep residential boreholes, farms, schools, and off-grid water supply systems.

This model uses a screw (progressive cavity) pumping mechanism, making it especially effective for high-head, low-flow applications. Screw pumps excel in deep wells by maintaining steady output with low power consumption and strong tolerance to variable solar conditions. Operating on 72V DC, the pump runs directly from solar panels without an inverter, reducing system losses and long-term operating costs.

Its 3-inch stainless-steel body and 1″ outlet make it suitable for narrow and deep boreholes, while the brushless motor ensures quiet operation, low heat generation, and extended service life. Supplied and supported by Macire, this pump is fully tested and backed with expert system sizing, installation guidance, and after-sales support.

Mini FAQ

Q1: Why is this pump low-flow but high-head?
This is a screw pump, designed specifically for deep lifting with limited power availability.

Q2: Is this suitable for shallow boreholes?
It will work, but it is optimized for deep wells. Shallow boreholes are better served by centrifugal models.

Q3: Can it run on solar only?
Yes. It is designed for direct 72V DC solar operation.

Q4: Is it suitable for irrigation?
Best for tank filling and controlled supply, not high-volume irrigation.

Q5: Does Macire provide support?
Yes. Full technical and after-sales support is provided by Macire.
