0.40Kw 1.5m³ 105m Premier Brushless 3TG1.5-105-400W/48V 400W 0.54HP 1500L/h Borehole Submersible Water DC Pump (Screw Type)

The Premier Brushless 3TG1.5-105-400W/48V DC Borehole Submersible Water Pump is a high-head, low-flow solar screw pump engineered for deep boreholes up to 105 meters. Powered by a 400W (0.40kW / 0.54HP) brushless DC motor, this pump delivers a steady 1.5 m³/h (1500 L/h) flow, making it ideal for deep wells where lift is critical and controlled flow is required.

Unlike centrifugal pumps, this model uses a screw (progressive cavity) pumping mechanism, which excels in deep lifting, low power consumption, and stable output under variable solar conditions. Operating on 48V DC, it runs directly from solar panels with no inverter required, reducing losses and total system cost.

The 3-inch stainless-steel body and 1″ outlet make it compact, efficient, and suitable for narrow or deep boreholes. Supplied and supported by Macire, this pump is 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 to lift water from deep levels efficiently using low power.

Q2: Is this better than centrifugal pumps for deep wells?
Yes. Screw pumps perform better at deep lifts with limited power.

Q3: Can it run on solar only?
Yes. It is designed for direct 48V DC solar operation.

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

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