- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU1800 HRE-03H Submersible Solar Pump is a professional unit (Pump Unit) designed for maximum lift with moderate flow rates. It integrates the high-efficiency ECDrive 1800-HRE brushless motor and the HRE-03H helical hydraulics in AISI 304/316 stainless steel with an integrated check valve. It is capable of reaching up to 240 m in height with a reference flow rate of 0.43 m³/h, making it an ideal option for very deep wells, high-elevation tanks, and long pipelines. As a PU version, it includes pump + motor, but does not include a controller; it must be combined with a compatible Lorentz controller for operation with solar energy.
Main Features
- Helical HRE-03H hydraulics optimized for high pressure with controlled flow.
- Reference flow rate 0.43 m³/h and lift up to 240 m.
- ECDrive 1800-HRE motor (~1.7 kW), brushless, IP68, maintenance-free.
- Robust construction in AISI 304/316 and integrated check valve.
- Lorentz ecosystem: spare parts available and compatibility with high-power PS2 controllers.
Advantages or Benefits
- Ability to extract water from extreme depths with optimized solar consumption.
- Reduced operating cost due to the high-efficiency brushless motor and high-performance hydraulics.
- Protection of the installation (column and pipes) thanks to the integrated check valve.
- Simple installation and service thanks to the modular design and availability of spare parts.
Purpose or Applications
Water extraction in very deep wells, high-elevation tanks, drip irrigation on steep slopes, and livestock in remote areas. Ideal when the priority is pressure/lift with moderate flow rates.
Technical Specifications
| Height / Reference Flow Rate | Up to 240 m / 0.43 m³/h |
| Hydraulic Type | Helical (HRE-03H) with check valve |
| Motor | ECDrive 1800-HRE, ≈1.7 kW, 900–3,300 rpm, IP68 |
| Materials | AISI 304/316 stainless steel |
| Borehole Diameter | ≥ 4” |
| Water Temperature | ≤ 50 °C (typical) |
| Maximum Submersion | Up to 150 m (depending on installation) |
| Protection Rating | IP68 (submersible unit) |
Compatibilities
Requires a compatible Lorentz controller, typically PS2-1800 for this power rating. The PV array must be sized according to the controller's limits (Voc/Isc and MPPT window), without restricting panel brands. Recommended accessories: dry well probe, tank sensor, DC protections, submersible cable, and column pipe/valves.
The Lorentz PU1800 HRE-03H Submersible Solar Pump offers the perfect combination of high lift, robustness, and efficiency for solar pumping projects in very deep wells.
