- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU1800 HRE-03 Submersible Solar Pump is a professional unit (Pump Unit) designed to achieve great height with moderate flow rates. It integrates the brushless ECDrive 1800-HRE motor and the HRE-03 helical hydraulics in AISI 304/316 with a non-return valve. It provides a reference flow rate of 0.43 m³/h and reaches 120 m of lift, ideal for 4” wells with long pipelines and elevated tanks. As a PU version, it includes pump + motor, but does not include controller.
Main Features
- Reference flow rate 0.43 m³/h and lift up to 120 m.
- ECDrive 1800-HRE motor (~1.7 kW), brushless, IP68, maintenance-free.
- HRE-03 helical head with integrated non-return valve; AISI 304/316 materials.
- Lorentz modular design with official spare parts and full compatibility with PS2 controllers.
Advantages or Benefits
- High water column with optimized solar consumption and very low operating cost.
- Long service life thanks to mechanical simplicity and stainless materials.
- Installation protection: the integrated valve reduces water hammer and emptying.
- Simple installation and service due to its modular architecture.
Purpose or Applications
Water extraction in deep wells, tanks at medium/high elevation, drip irrigation, and livestock in remote areas where pressure/height is prioritized over flow rate.
Technical Specifications
