Lorentz PU1800 HRE-05HL Submersible Solar Pump 0.97 m³/h 250 m Helicoidal
Modelo: PU1800 HRE-05HL- Sku: LOREBOM054
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU1800 HRE-05HL Submersible Solar Pump is a professional 4” pumping unit for very deep wells. It combines high-pressure HRE-05HL helical hydraulics with a brushless ECDrive 1800-HRE motor to deliver up to 0.97 m³/h at 250 m head. Its AISI 304/316 stainless steel body and integrated check valve ensure durability and protection of the water column in demanding installations. Important: controller not included; must be paired with a compatible Lorentz controller.
Main Features
- Optimized helical hydraulics for high lift: up to 250 m with a reference flow rate of 0.97 m³/h.
- Industrial-grade AISI 304/316 materials for high corrosion resistance.
- Integrated check valve that minimizes water hammer and protects the installation.
- High-efficiency ECDrive 1800-HRE motor, IP68, maintenance-free.
- Lorentz modular architecture: spare parts and technical service readily available.
Advantages or Benefits
- Pumping capacity in very deep wells while maintaining a continuous and stable flow rate.
- Reduced operating costs thanks to the brushless motor and overall efficiency.
- Longer system lifespan due to robust construction and built-in check valve.
- Integration flexibility: can operate with different Lorentz controllers depending on project requirements.
Purpose or Applications
Water supply for off-grid homes, elevated tanks, drip irrigation on slopes, livestock, and rural projects requiring a high water column with solar energy. Ideal when high pressure is needed with moderate flow rates.

Compatibilities
Requires compatible Lorentz controller (not included). It is ideal with controllers from the PS2-1800 family or equivalent from the manufacturer when high head is required. Supports photovoltaic arrays sized to respect the electrical limits of the chosen controller (Voc voltage and input current). Common accessories: dry well sensors, tank probes, DC protections, submersible cable, valves, and column piping. For panels, use modules that meet the controller’s voltage/current requirements regardless of brand or model.
The Lorentz PU1800 HRE-05HL Submersible Solar Pump is the perfect modular solution when maximum lift, reliability, and minimal maintenance are required in professional solar pumping projects.
