Lorentz PE HRE-14H Hydraulic Body for submersible solar pump
Modelo: 12-005120 PE HRE-14H-3, Rp 1 1/4"- Sku: LOREREP038
- Vendor: Lorentz
Specifications
Product description
The Lorentz PE HRE-14H Hydraulic Body is the professional helical end for 4" submersible solar pumps. Designed to work with Lorentz ECDrive HRE motors, it provides high thrust with flow rates up to 2.7 m³/h and manometric heads up to 120 m (values obtained when combined with the ECDrive 1800-HRE motor and the appropriate controller). Its construction in AISI 304/316 stainless steel and its integrated check valve ensure reliability, hydraulic safety, and long service life in irrigation, livestock, and domestic supply applications in off-grid or hybrid environments.
Main features
- HRE-14H helical stage with high thrust for great heights and stable pressure.
- Target performance of the assembly: up to 2.7 m³/h and 120 m with ECDrive 1800-HRE motor.
- Robust construction in AISI 304/316 stainless steel for maximum corrosion resistance.
- Integrated check valve that prevents column backflow and water hammer.
- Modular format: independent replacement of the hydraulic end without changing the motor.
- Suitable for 4" boreholes (minimum well diameter according to the ECDrive series).
Advantages or benefits
- Greater reliability and lower maintenance thanks to premium materials and precise tolerances.
- Superior efficiency at low irradiance due to its helical design, ideal for solar energy.
- Hydraulic safety: the integrated valve protects pipes, fittings, and the tank.
- Reduced total cost: modular architecture that enables quick and economical repairs.
- Performance adapted for sprinkler irrigation, drip irrigation, or filling elevated tanks.
Purpose or applications
Replacement or installation of submersible solar pumps for agricultural irrigation (drip/sprinkler), water supply to homes and farms, livestock drinking troughs, cistern filling stations, and small pressurized networks where high pressure must be maintained at great heights with photovoltaic energy.
