Lorentz PU600 HRE-03 Solar Submersible Pump 0.45 m³/h 120m Helicoidal

Product Description

The Lorentz PU600 HRE-03 Solar Submersible Pump is a professional pumping unit (Pump Unit) designed to operate with solar energy in 4” wells. It combines the HRE-03 helical hydraulics—specialized in generating high pressure with moderate flow rates—with a brushless ECDrive motor from the 600 series. This configuration allows for a reference flow rate of 0.45 m³/h and can reach up to 120 m of manometric head, making it ideal for elevated tanks, long pipelines, or installations with significant elevation differences. Its construction in AISI 304/316 stainless steel and the integrated check valve ensure reliability, protection of the water column, and a long service life. Important: as a PU version, it includes pump + motor, but does not include the controller, which must be selected separately.

Main Features

• HRE-03 helical hydraulics optimized for high head in 4” wells.
• Reference flow rate of 0.45 m³/h and lift up to 120 m, perfect for deep wells.
• ECDrive 600 series motor, brushless, IP68, high efficiency, and minimal maintenance.
• Robust construction in AISI 304/316 at critical parts for maximum corrosion resistance.
• Integrated check valve that prevents column drainage and reduces water hammer.

Advantages or Benefits

• Large water column with optimized solar consumption, ideal when pressure is prioritized over flow rate.
• Very low total cost of ownership: brushless motor, absence of brushes, and simple architecture.
• Professional reliability thanks to stainless materials and built-in hydraulic protection.
• Simple integration into photovoltaic systems with Lorentz PS2 family MPPT controllers.
• Availability of spare parts and technical service within the Lorentz ecosystem.

Purpose or Applications

Supply for isolated homes, filling of tanks at medium/high elevation, livestock, and drip irrigation on slopes. Suitable for long pipelines, connections to elevated tanks, and solar pumping projects in remote areas where high pressure with contained flow rates is required.

Technical Specifications

Compatibilities

For solar operation, a compatible Lorentz controller (not included) is required, with the PS2-600 being common for this power range. The photovoltaic array must be sized according to the controller’s electrical limits (open-circuit voltage, input current, and MPPT window); it is not limited to panel brands. Common and recommended accessories: dry well probe, tank sensor, DC protections, submersible cable, and column piping/valves.

The Lorentz PU600 HRE-03 Solar Submersible Pump is the efficient and robust choice for solar pumping systems that demand sustained high pressure, reliability, and minimal maintenance.
