Lorentz PU600 HRE-04H Solar Submersible Pump 0.72 m³/h 140m Helicoidal

Product Description

The Lorentz PU600 HRE-04H Solar Submersible Pump is a professional pumping unit designed to extract water from deep wells using solar energy. It integrates HRE-04H helical hydraulics and a high-efficiency ECDrive brushless motor to deliver a reference flow rate of 0.72 m³/h and reach up to 140 m of manometric head. Its AISI 304/316 stainless steel construction and the built-in check valve ensure reliability, protection of the water column, and long service life in demanding environments. Important: controller not included; it must be combined with a compatible Lorentz controller (usually PS2-600) and a properly sized photovoltaic array.

Main Features

• HRE-04H helical hydraulics optimized for high pumping head with moderate flow rates.
• 0.72 m³/h reference flow and up to 140 m lift in 4” wells.
• Submersible ECDrive motor, brushless, IP68, high efficiency, and minimal maintenance.
• Robust construction in AISI 304/316 with integrated check valve.
• Lorentz modular architecture: spare parts, service, and scalability within the same ecosystem.

Advantages or Benefits

• High water column with optimized solar consumption, ideal for elevated tanks and uneven terrain.
• Lower operating costs compared to AC pumps: brushless motor, fewer wear parts, and high efficiency.
• Enhanced hydraulic safety thanks to the check valve, which reduces water hammer.
• Easy integration with Lorentz controllers (PS2-600) and level/dry well sensors.
• Outstanding durability in continuous applications due to its materials and sealing.

Purpose or Applications

Designed for domestic and community water supply, filling elevated tanks, livestock, drip irrigation, and rural projects where pumping head is prioritized over flow rate. Performs especially well in off-grid or hybrid solar installations requiring high pressure.

Technical Specifications

Compatibilities

Requires a compatible Lorentz controller (not included); the usual option is the PS2-600 controller for this power rating. Supports photovoltaic arrays from various brands as long as the electrical limits of the selected controller are respected (open-circuit voltage, input current, and MPPT range). Common accessories: dry well probe, tank sensor, DC protections, submersible cable, and column pipe.

The Lorentz PU600 HRE-04H Solar Submersible Pump offers the ideal combination of high lift, robustness, and energy efficiency for solar pumping projects in deep wells with sustained pressure demand.
