Specifications
Product Description
The Lorentz PU1800 HRE-07 1.3 m³/h 120 m Submersible Solar Pump is a modular pump unit designed for 4” wells that require high pressure with moderate flow. It integrates the brushless ECDrive 1800-HRE motor (≈1.7 kW) and the HRE-07 helical hydraulics in AISI 304/316 stainless steel with a non-return valve. As a PU version, controller not included, allowing you to choose the most suitable electronics (recommended Lorentz PS2-1800) according to the PV array, protections, and control logic.
Main Features
- Flow/Head: up to 1.3 m³/h and 120 m, ideal for elevated tanks and irrigation at high elevation.
- ECDrive 1800-HRE high-efficiency brushless motor, sealed, IP68; minimal maintenance.
- HRE-07 helical hydraulics with integrated non-return valve, high performance at high pressure.
- Robust construction in AISI 304/316 for maximum corrosion resistance.
- Modular architecture: replace/upgrade the controller without changing the pump unit.
- Typical immersion up to 150 m (depending on installation and cabling).
Advantages or Benefits
- Total flexibility to size the control and PV array for your project.
- More daily water with less energy thanks to the brushless motor and helical hydraulics.
- Low operating cost and long service life due to stainless materials and IP68 protection.
- Hydraulic safety with integrated valve that prevents backflow and water hammer.
- Quiet and reliable for continuous operation in remote environments.
Purpose or Applications
Supply to elevated tanks on significant slopes, sprinkler/drip irrigation on high-elevation farms, small distribution networks, and livestock when high pressure is needed with a flow of ~1.3 m³/h.
