300W 3HR Solar Borehole Pump Kit, 48 V DC, 100 m Head, 2 m³/h

Description

Overview

The 300W 3HR is a 48 V DC solar borehole pump kit in 304 stainless steel, lifting water up to 100 m at up to 2 m³/h, with its matching DC controller in the kit.

It goes into any borehole, well, river, dam or tank with an internal diameter of 80 mm (3 inches) or more, and suits non-corrosive water with sand below 1 percent by volume, particles under 0.5 mm, up to 40 °C and pH 6.5 to 8.5. The controller soft-starts the motor and guards against under-voltage, over-voltage, over-pumping, overloading and dry running, restarting on its own when water returns. The 304 stainless steel 3HR range resists corrosion better than the 201 range, so it suits harder or saline water, and it extends to deeper 140 m and 180 m head models.

Key features

• Pump body and casing in 304 stainless steel, with stainless steel shaft and coupling
• 100% copper windings, graphite bearings and a wear-resistant rubber stator
• Brushless DC motor with its matching DC controller in the kit
• Soft start with automatic recovery after a dry-run stop
• Compact, low-noise, maintenance-free construction
• Duty points: 8.3 L/min at 85 m, 16.6 L/min at 65 m, 25 L/min at 28 m
• Solar array of about 600 W (two 400 W panels) recommended

Where it works

Solar pumping suits farm water points in Mpumalanga, small irrigation plots, village standpipes and any site where the grid is far or load-shedding keeps stopping the pump. Size the pump on your water level, the depth to the water rather than the borehole depth, and choose at least 25 to 30 percent more head to cover friction losses and a falling water table. Our guide for this model is water levels up to about 75 m.
