Lorentz PU1800 HRE-10 Submersible Solar Pump 2.1 m³/h 80 m Helicoidal

Product Description

The Lorentz PU1800 HRE-10 2.1 m³/h 80 m Submersible Solar Pump is a modular pump unit designed for solar installations that require high pressure and a flow rate close to 2 m³/h. It combines the brushless ECDrive 1800-HRE motor of 1.7 kW with the HRE-10 helical hydraulics in AISI 304/316 stainless steel and an integrated check valve, ensuring maximum reliability in 4” wells. As a PU version, controller not included: it allows you to choose the most suitable electronics (PS2-1800 recommended) to adapt the control strategy, protections, and communications to your project.

Main Features

• Flow rate and head: up to 2.1 m³/h and 80 m for 4” cased wells.
• ECDrive 1800-HRE Motor brushless (nominal ~1.7 kW), sealed, high efficiency, and IP68.
• PE HRE-10 Helical Hydraulics with max. efficiency ~67% and integrated check valve.
• Robust construction in AISI 304/316 for corrosion resistance and long service life.
• Modular architecture: replace/upgrade the controller without changing the pump unit.
• Typical immersion up to 150 m (depending on cabling and installation conditions).

Advantages or Benefits

• Total flexibility: select the controller (PS2-1800 or other compatible) according to your PV array and control logic.
• More water per day with the same solar power thanks to the helical hydraulics and high-efficiency motor.
• Low operating cost: brushless motor, stainless steel materials, and minimal maintenance.
• Scalable and repairable: modular design that facilitates expansions, replacements, and service.
• Extreme reliability in remote environments due to its IP68 sealing and built-in check valve.

Purpose or Applications

Supply for isolated homes, filling elevated tanks, drip or light sprinkler irrigation, and livestock when high pressure with moderate flow is required. Excellent option for autonomous photovoltaic systems with varying irradiation and constant daily demands.

Technical Specifications

Compatibilities

Integrates with controllers for ECDrive motors, especially Lorentz PS2-1800, as long as the electrical limits defined by the selected controller and PV sizing are respected. Suitable for supply and irrigation systems that meet the project's flow/head requirements.

The Lorentz PU1800 HRE-10 2.1 m³/h 80 m provides modularity, efficiency, and robustness for professional solar installations that require high pressure and customized control.
