Lorentz PU4000 HRE-14HL Submersible Solar Pump 2.6 m³/h 180 m

Product Description

The Lorentz PU4000 HRE-14HL Submersible Solar Pump is a high-pressure Pump Unit for 4” wells. It combines the 4.0 kW ECDRIVE 4000-HRE motor with the PE HRE-14HL helical head, made of AISI 304/316 stainless steel and equipped with a check valve. Supplied without controller for integration with a new or existing PS2-4000, allowing the system to be designed according to the available PV array. With the appropriate controller, it achieves up to 2.6 m³/h and 180 m, ensuring stable flow, efficiency, and very low maintenance.

Main Features

• ECDRIVE 4000-HRE brushless motor, water-filled, IP68, maintenance-free.
• PE HRE-14HL helical head with check valve, high efficiency (≈74%).
• Performance of the set (with PS2-4000): 2.6 m³/h and 180 m head.
• AISI 304/316 stainless steel materials and modular architecture for quick servicing.
• Compact and quiet design, optimal for continuous solar pumping in 4” wells.

Advantages or Benefits

• Total flexibility: renew only the submersible part or create a custom system with PS2-4000.
• Low operating cost thanks to brushless technology and efficient helical hydraulics.
• Reliability and long service life due to stainless steel construction and IP68 rating.
• Lorentz modularity allows independent replacement of motor or head.

Purpose or Applications

Pressurized irrigation, elevated tanks, long-distance transfers, and supply for agricultural and livestock operations requiring high head with photovoltaic energy.

Technical Specifications

Compatibilities

Direct compatibility with Lorentz PS2-4000 Controller and standard discharge accessories for 4” wells. Through the controller, it supports dry well probes, float switches, and remote control. For the PV array, size the strings within the PS2-4000 window (Vmp/Voc and Isc in range).

The Lorentz PU4000 HRE-14HL is the modular and robust option for solar pumping projects that demand high pressure with maximum efficiency and reliability.
