Lorentz PU1800 HRE-04H Submersible Solar Pump 0.72 m³/h 140 m Helicoidal

Product Description

The Lorentz PU1800 HRE-04H Submersible Solar Pump is a high-performance pumping unit for deep wells. It combines HRE-04H helical hydraulics with a high-efficiency ECDrive motor to deliver up to 0.72 m³/h and lift water up to 140 m. Constructed from AISI 304/316 stainless steel and integrated with a check valve, it ensures long-term reliability in demanding applications such as drinking water, livestock, and irrigation. Important: controller not included; must be paired with a compatible Lorentz controller.

Main Features

• Optimized helical hydraulics for high head (up to 140 m).
• Reference flow rate of 0.72 m³/h with stable and efficient operation on solar energy.
• Submersible brushless ECDrive motor, IP68, maintenance-free.
• Constructed from AISI 304/316 with integrated check valve to protect the column.
• Lorentz modular architecture: easy component replacement and technical service.

Advantages or Benefits

• High performance in deep wells with optimized energy consumption.
• Long service life thanks to premium materials and the simplicity of the assembly.
• Hydraulic safety and reduction of water hammer due to the check valve.
• Flexibility to select the most suitable controller according to the project.

Purpose or Applications

Residential and community water supply, elevated tanks, drip irrigation on steep slopes, and livestock in remote areas. Especially recommended when pumping height is prioritized over flow rate.

Technical Specifications

Compatibilities

Requires a compatible Lorentz controller (not included). Size the photovoltaic array according to the controller’s limits (open-circuit voltage and input current; Vmp within the MPPT window). Common accessories: dry well probe, tank sensor, DC protections, submersible cable, valves, and column piping. Not restricted to panel brands; the key is to respect the electrical parameters.

The Lorentz PU1800 HRE-04H Submersible Solar Pump stands out for its balance between high lift, reliability, and low maintenance, delivering professional results in deep well solar pumping.
