Lorentz PE HRE-23 Hydraulic Body for submersible solar pump
Modelo: 12-005390 PE HRE-23-3, Rp 1 1/4"- Sku: LOREREP039
- Vendor: Lorentz
Specifications
Product description
The Lorentz PE HRE-23 Hydraulic Body is the original helicoidal stage for 4" submersible solar pumps, designed to deliver high thrust with flow rates up to 3.9 m³/h and heads up to 80 m. Manufactured in AISI 304/316 stainless steel and with an integrated check valve, this hydraulic end couples to the Lorentz ECDrive HRE motor to form a robust, efficient, and durable pumping solution for irrigation, livestock, and potable water supply.
Main features
- HRE-23 helicoidal design: high thrust and stable performance at medium-high elevations.
- Max. flow rate 3.9 m³/h and max. head 80 m when combined with ECDrive 1800-HRE motor.
- Constructed in AISI 304/316 stainless steel for maximum corrosion resistance.
- Integrated check valve that protects the column and prevents water hammer.
- Modular format: replacement of the hydraulic end without changing the motor or electronics.
- Compatible with 4" wells and direct connection to Lorentz ECDrive HRE motors.
Advantages or benefits
- Greater reliability: premium materials and tight tolerances for continuous operation.
- Reduced maintenance: sealed architecture and long-life components.
- Solar energy efficiency: the helicoidal design optimizes performance at low irradiance.
- Simple servicing: as an independent hydraulic body, it reduces repair costs and downtime.
- Safe operation: the check valve prevents water backflow and protects the system.
Purpose or applications
Ideal for off-grid or hybrid solar installations with backup: drip or sprinkler irrigation, filling elevated tanks, domestic supply on farms, livestock watering, and small pressurized networks. Its combination of flow rate and head makes it suitable for wells with demanding dynamic levels.
