Lorentz PU600 HRE-04 Solar Submersible Pump 0.72 m³/h 70m Helicoidal

Product Description

The Lorentz PU600 HRE-04 Solar Submersible Pump is a professional pumping unit designed to extract water from 4” wells using solar energy. It combines the HRE-04 helical hydraulics—optimized for high pressure with moderate flow rates—and the brushless ECDrive motor from the 600 series, offering a reference flow rate of 0.72 m³/h and a manometric head of up to 70 m. Its construction in AISI 304/316 stainless steel and the integrated check valve provide mechanical reliability, protection of the water column, and long service life in demanding environments. Important: this is a PU (Pump Unit), so it includes pump + motor, but does not include controller; it must be combined with a compatible Lorentz controller for solar operation.

Main Features

• HRE-04 helical hydraulics for high head with excellent performance on solar energy.
• Reference flow rate 0.72 m³/h and lift up to 70 m in wells ≥ 4”.
• ECDrive 600 series motor, brushless, IP68, and maintenance-free.
• Quality materials: AISI 304/316 stainless steel in critical areas.
• Integrated check valve that reduces water hammer and protects the system.

Advantages or Benefits

• High water column with optimized solar consumption and very low operating costs.
• Robust and simple architecture, with spare parts and service within the Lorentz ecosystem.
• Hydraulic and electrical safety when combined with PS2 controllers with integrated protections.
• Minimal maintenance thanks to the brushless motor and high-efficiency hydraulics.

Purpose or Applications

Especially suitable for domestic supply, filling tanks at medium elevation, livestock, and drip irrigation on slopes, when the priority is to achieve pumping height with stable flow and solar energy.

Technical Specifications

Compatibilities

Requires external controller (PS2-600 recommended) and a PV array sized according to the voltage/current admissible by the controller (no panel brand limitation). Usual accessories: dry well probe, tank sensor, DC protections, submersible cable, and column pipe.

The Lorentz PU600 HRE-04 Solar Submersible Pump is the reliable and efficient choice for solar pumping projects that require good manometric head with contained consumption.
