Specifications
Product Description
The Lorentz PU1800 HRE-07H 1.4 m³/h 160 m Submersible Solar Pump is a modular pump unit (PU) designed for solar projects that require high pressure and moderate flow in 4” wells. It combines the brushless ECDrive 1800-HRE motor (1.7 kW) with the HRE-07H helical hydraulics, made of AISI 304/316 stainless steel and featuring an integrated check valve. This version does not include a controller, allowing you to select the most suitable electronics for your photovoltaic field (Lorentz PS2-1800 with MPPT recommended). The result is a robust, efficient set, ideal for high-head pumping with minimal maintenance.
Main Features
- Flow/Head: up to 1.4 m³/h and 160 m, ideal for deep 4” wells.
- ECDrive 1800-HRE Motor: 1.7 kW, brushless, sealed, and highly efficient, with IP68 protection.
- HRE-07H Hydraulics: helical screw optimized for high heads; integrated check valve.
- Construction in AISI 304/316 stainless steel for maximum durability and corrosion resistance.
- Modular architecture: allows you to choose/upgrade the controller without changing the pump unit.
- Typical immersion up to 150 m (depending on cabling, losses, and installation conditions).
Advantages or Benefits
- Total flexibility: select the controller (PS2-1800 or other compatible) that best suits your PV generator, probes, and automation.
- More water with less energy: the helical hydraulics maintain daily performance even with variable irradiation.
- Low operating cost: brushless motor and stainless materials reduce maintenance and downtime.
- Hydraulic safety: the integrated check valve prevents backflow and water hammer.
- Long service life: industrial design, IP68, and premium components for intensive use in remote environments.
Purpose or Applications
Especially recommended for supplying elevated tanks at significant heights, sprinkler irrigation on sloped plots, small distribution networks, livestock, and long-distance transfer in 4” intakes. Its best performance is achieved when high pressure is required with flows around 1–1.4 m³/h.
