Description
The Lorentz PS200 HR-07-3 Submersible Pump System is a high-efficiency DC solar-powered helical rotor pump engineered for reliable water supply from boreholes and wells. Purpose-built for solar operation, it delivers consistent flow at medium heads with excellent energy efficiency—making it ideal for domestic water supply, livestock watering, and small irrigation projects.
At the core of the system is a maintenance-free ECODRIVE DC motor, a durable HR-07 helical rotor pump end, and the intelligent PS2-200 controller. Together, they ensure dependable performance in remote locations where grid power is unavailable or unreliable.
Performance Overview
| Operating Condition | Daily Output | Recommended Solar Array |
| @ 40 m Head | ~6,000 litres/day | 2 × 300 W solar panels |
| @ 25 m Head | ~6,000 litres/day | 1 × 330 W solar panel |
Actual performance depends on site conditions, solar irradiation, and installation.
