Lorentz PE HRE-07 Hydraulic Body for submersible solar pump

Product Description

The Lorentz PE HRE-07 Hydraulic Body is a helicoidal pump end for 4” submersible solar pumps, designed to provide high head with stable flow. Manufactured from AISI 304/316 stainless steel and featuring an integrated check valve, it delivers reliability, performance, and low maintenance when combined with ECDrive motors and MPPT controllers.

Main Features

• Helicoidal (screw) hydraulics optimized for high pressures.
• Construction in AISI 304/316 stainless steel, highly resistant to corrosion.
• Integrated check valve to prevent siphoning and water hammer.
• Maximum hydraulic efficiency approximately ~70% (depending on configuration).
• For cased wells with diameter ≥ 4” and clean water ≤ 50 °C.
• Mechanical compatibility with ECDrive 200-HRE / 600-HRE / 1800-HRE.

Advantages or Benefits

• More daily water with compact PV fields thanks to the high performance of the helicoidal screw.
• Outstanding durability due to stainless materials and robust design.
• Minimal maintenance as it contains no electronics and includes an integrated valve.
• Common base for multiple motor/controller configurations, simplifying spare parts.

Purpose or Applications

Supply to elevated tanks, irrigation at medium-high elevations, livestock, and pressurized transfers in 4” intakes. Ideal when flows of ~1.3 m³/h are required at high heads.

Technical Specifications

Compatibilities

Part of the PU200/PU600/PU1800 HRE-07 units and systems with PS2-200/PS2-600/PS2-1800 HRE-07 controllers. Integrates with solutions using well/tank sensors, pressure switches, and automation depending on the controller.

The Lorentz PE HRE-07 is the ideal base for high-pressure solar pumps: robust, efficient, and versatile.
