0.4Kw 3.5m³ 55m Premier Brushless 4TY3.5-55/7-400W/48V 400W 0.54HP 3500L/h Borehole Submersible Water DC Pump

The Premier Brushless 4TY3.5-55/7-400W/48V DC Borehole Submersible Water Pump is a high-efficiency solar pumping solution designed for boreholes up to 55 meters. Powered by a 400W (0.4kW / 0.54HP) brushless DC motor, this pump delivers a reliable 3.5 m³/h (3500 L/h) flow, making it ideal for domestic water supply, rural homes, and small-scale agricultural use.

The brushless motor technology ensures higher efficiency, quieter operation, and longer service life compared to brushed DC pumps. Operating on 48V DC, the pump integrates seamlessly with solar-only or hybrid systems, making it well suited for off-grid installations across Kenya. Its 4-inch stainless-steel submersible body provides durability and corrosion resistance, while the 1.5″ outlet supports smooth water discharge at moderate depths.

Supplied and supported by Macire, this pump is verified before dispatch, with expert guidance on solar sizing, controller selection, installation, and long-term maintenance—ensuring dependable water supply where reliability matters.
