Modelo: 10-017790 PU200 HRE-04-3, Rp 1 1/4", UL- Sku: LOREBOM028
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU200 HRE-04 Solar Submersible Pump is a compact and highly efficient unit for solar pumping in 4” wells. It integrates the HRE-04 helical head —which prioritizes pressure over flow rate— with the brushless ECDrive motor from the 200 series. It offers a reference flow rate of 0.73 m³/h and reaches up to 50 m of manometric head, making it an ideal solution for low to medium elevation tanks, domestic supply, and localized irrigation. Like all PU units, it includes pump + motor, but does not include the controller, which must be selected according to the project requirements.
Main Features
- Helical HRE-04 hydraulics with excellent performance in solar energy.
- Reference flow rate of 0.73 m³/h and head up to 50 m.
- ECDrive 200 series motor, brushless, IP68, maintenance-free.
- Construction in AISI 304/316 stainless steel and integrated check valve.
- Lorentz modular design for easy servicing and spare parts availability.
Advantages or Benefits
- Economical and robust solution with very low solar consumption.
- Lower ownership cost due to the absence of brushes and high overall efficiency.
- Installation protection when combined with PS2 controllers with dry well and tank inputs.
- Simple installation and maintenance in residential and rural projects.
Purpose or Applications
Supply for isolated homes, tank filling, small livestock farms, and drip irrigation. Suitable when moderate head is required and maximum efficiency is valued with a small PV array.
Technical Specifications
| Head / Reference Flow Rate | Up to 50 m / 0.73 m³/h |
| Hydraulic Type | Helical (HRE-04) with check valve |
| Motor | ECDrive 200 (brushless), IP68, 900–3,300 rpm (typ.) |
| Materials | AISI 304/316 stainless steel |

Compatibilities
To operate with solar energy, a compatible Lorentz controller is required (typically PS2-200) and a PV array sized according to the controller’s electrical limits (Voc/Isc and MPPT window); it is not restricted to panel brands. Recommended accessories: dry well probe, tank sensor, DC protections, submersible cable, and riser pipe.
The Lorentz PU200 HRE-04 Solar Submersible Pump provides reliability, simplicity, and efficiency for small and medium-scale solar pumping projects.
