0.25Kw 1.5m³ 70m Premier Brushless 3TG1.5-70-250W/24V 250W 0.34HP 1500L/h Borehole Submersible Water DC Pump (Screw Type)

The Premier Brushless 3TG1.5-70-250W/24V DC Borehole Submersible Water Pump is a compact, low-power solar screw pump engineered for shallow to mid-depth boreholes up to 70 meters. Powered by a 250W (0.25kW / 0.34HP) brushless DC motor, it delivers a steady 1.5 m³/h (1500 L/h) flow while operating efficiently on a 24V DC solar system.

This model is ideal for homes, small farms, rural water supply, and off-grid applications where power availability is limited but reliable water lifting is required. Its screw (progressive cavity) pump design ensures consistent output even under fluctuating solar conditions, making it a dependable choice for direct solar pumping without the need for an inverter.

Built with a 3-inch stainless-steel body and a 1″ outlet, the pump fits easily into narrow boreholes and offers long service life with minimal maintenance. Supplied and supported by Macire, it comes as a complete kit with controller and accessories, ready for installation.
