- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU1800 HRE-14H Submersible Solar Pump is a professional pump unit (motor + hydraulic head) for 4" wells. It combines the high-efficiency ECDrive 1800-HRE motor with the HRE-14H helical end, achieving up to 2.7 m³/h with a head of 120 m. This PU version does not include a controller, allowing integration with the appropriate Lorentz controller for your photovoltaic field and automation needs.
Main Features
- Max flow: 2.7 m³/h; max head: 120 m (high-thrust helical for high pressure).
- ECDrive 1800-HRE motor, 1.7 kW, brushless, water-filled, IP68, immersion up to 150 m.
- PE HRE-14H pump head with check valve; high hydraulic efficiency and stable operation.
- Premium materials in AISI 304/316 stainless steel for long service life and corrosion resistance.
- Water temperature up to 50 °C; intensive use for irrigation, tanks, and domestic supply.
Advantages or Benefits
- Sustained pressure at great heights thanks to the helical design, ideal for sprinklers and elevated networks.
- Reduced maintenance: brushless motor without submerged electronics and modular components.
- System flexibility: choose the PS2-1800 controller and the PV configuration that best suits the project.
- Simple servicing: independent replacement of motor or hydraulic body reduces costs and downtime.
- Industrial robustness for continuous operation in demanding environments.
Purpose or Applications
Agricultural irrigation (drip/sprinkler), tank filling, livestock watering, water supply in isolated homes, and small pressurized networks powered by solar energy.

Compatibilities
Direct compatibility with Lorentz PS2-1800 controller (required for operation), level sensors, and DC protection accessories. Regarding the PV field, compatibility depends on the controller used: size the string to meet Vmp of the array > 102 V and total VOC < 200 V on the PS2-1800. Suitable for off-grid solar systems, hybrid systems with backup, and direct pumping applications.
Lorentz PU1800 HRE-14H Submersible Solar Pump is the modular and robust option for high-head solar pumping, minimizing maintenance and maximizing reliability.
