Lorentz PU4000 HRE-32 Submersible Solar Pump 5.9 m³/h 120 m

Product Description

The Lorentz PU4000 HRE-32 Submersible Solar Pump is a high-flow pump unit that combines the ECDRIVE 4000-HRE 4.0 kW motor with the HRE-32 helical head in AISI 304/316 stainless steel and a non-return valve. This version is supplied without controller, making it perfect for integration with an existing PS2-4000 or for designing a custom system according to the available photovoltaic array. Together with the appropriate controller, it delivers up to 5.9 m³/h and 120 m, with quiet, efficient, and virtually maintenance-free operation.

Main Features

• ECDRIVE 4000-HRE motor (DC, brushless) 4.0 kW, 900–3300 rpm, IP68; no electronics in the motor and water-filled.
• PE HRE-32 head of helical type in AISI 304/316 with integrated non-return valve.
• Performance of the set with PS2-4000: 5.9 m³/h and 120 m under optimal conditions.
• Lorentz modular architecture: independent replacement of hydraulics, motor, or controller.
• Premium materials and robust design for intensive use in clean water.

Advantages or Benefits

• Total flexibility: renew only the submersible part or configure a new system with PS2-4000.
• Minimal operating cost due to sealed brushless technology and high hydraulic efficiency.
• High flow rate sustained in 4” wells, ideal for irrigation and tank filling.
• Hydraulic safety with check valve that prevents backflow and water hammer.

Purpose or Applications

Drip/sprinkler irrigation, medium-distance transfers, supply to agricultural and livestock operations, and filling of ponds or tanks where flow rate is prioritized with columns up to 120 m.

Technical Specifications

Compatibilities

Direct compatibility with Lorentz PS2-4000 Controller and standard 1.5” discharge accessories. Through the controller, it supports dry well probes, float switches, and remote control. For the PV generator, size strings within the PS2-4000 window (Vmp/Voc and Isc in range).

The Lorentz PU4000 HRE-32 is the modular and robust option for high-flow solar pumping systems: efficiency, reliability, and total adaptation to your project.
