CYCLONE 3" DC Brushless Screw Solar Borehole Pump

The Solar Pal PV CYCLONE is a 3" DC brushless screw (helical rotor) solar borehole pump designed for off-grid and load-shedding-resilient water supply. It runs directly off solar panels via its low-voltage DC brushless motor and screw pump element, making it a practical choice for farmers, borehole users and rural or off-grid properties that need reliable water without relying on mains power.

• Application: Suitable for solar-powered borehole water supply, off-grid pumping and load-shedding backup
• Key specification: 3" diameter, DC brushless screw pump, 210W-500W depending on model
• Borehole compatibility: 3" pump diameter, suitable for 4" and larger boreholes
• Solar panels: Sold separately — CYCLONE-77 needs 1 x 330W panel, CYCLONE-109 needs 2 x 330W panels
• Installation: Supplied complete with an installation pack, 1 x float switch and DC controller

Key Features

• Brushless DC motor with screw (helical rotor) pumping element for efficient low-flow, high-head solar pumping
• Runs directly from solar panels through the included DC controller — no need for mains AC power or a separate inverter
• Compact 3" body fits standard 4" and larger borehole casings
• Includes an installation pack and float switch (dry-run/tank-full protection) as standard
• Helical rotor is a genuine spare part (SKU CYC-HR), so the pump element can be serviced rather than replacing the whole unit

Typical Applications

• Off-grid borehole water supply for homes, farms and rural properties
• Load-shedding-resilient household or farm water supply
• Livestock watering and irrigation from a borehole
• Remote sites with no reliable grid connection

Technical Specifications

What's Included

• 1 x CYCLONE solar borehole pump (model per variant selected)
• 1 x DC controller
• 1 x installation pack
• 1 x float switch

Please note: Solar panels, a weatherproof DC isolator, borehole cable extensions and mounting/wiring accessories beyond the installation pack are not included unless specifically listed above. A weatherproof DC isolator is required to isolate the panels for maintenance — refer to the ODD16 to 32D/E2/E4/E22 range for selection according to your application, or contact Zisabo for guidance.

Installation & Compatibility Notes

• Confirm which model you need based on your required head (water depth + friction/rising main losses) and flow — CYCLONE-77 for up to 77m head, CYCLONE-109 for up to 109m head.
• Size your solar panel array to the optimum input voltage range and minimum power shown in the spec table — panels are sold separately.
• Confirm your borehole diameter is 4" or larger before ordering — this is a 3" pump.
• A weatherproof DC isolator must be fitted between the panels and controller for safe maintenance isolation.
• Installation should be carried out by a suitably qualified installer.
