Lorentz PU1800 HRE-23 Submersible Solar Pump 3.9 m³/h 80 m Helicoidal
Modelo: 10-015500 PU1800 HRE-23-3, Rp1 1/4", UL- Sku: LOREBOM060
- Vendor: Lorentz
Specifications
Product description
The Lorentz PU1800 HRE-23 Submersible Solar Pump is a professional pump unit for 4" wells that combines a high-efficiency ECDrive motor with a helical HRE-23 hydraulic body. Delivers up to 3.9 m³/h with a head of 80 m, ideal for pressurized irrigation and potable water supply in off-grid environments. This PU (Pump Unit) version does not include a controller, allowing integration with the appropriate Lorentz controller for your photovoltaic field.
Main features
- Max. flow: 3.9 m³/h; max. head: 80 m (high-thrust helical).
- ECDrive 1800-HRE motor of 1.7 kW, high efficiency and IP68, submersible and maintenance-free operation.
- Hydraulic body PE HRE-23 in AISI 304/316 stainless steel with integrated check valve.
- Well diameter: 4" (minimum borehole 4.0"); max. immersion 150 m; water temperature up to 50 °C.
- Industrial-grade materials and seals for long service life in continuous pumping.
Advantages or benefits
- Stable thrust at high heads thanks to the helical design, ideal for sprinkler irrigation or filling elevated tanks.
- Minimal maintenance: brushless water-filled motor, no electronics in the submerged part.
- Robust stainless steel construction that withstands demanding environments and water with typical well mineral content.
- Modular architecture: independent replacement of the motor or hydraulic body to reduce service costs.
- Simple integration with Lorentz PS2 controllers to leverage MPPT, dry well protection, and telemetry.
Purpose or applications
Agricultural irrigation (drip, sprinkler), supply to isolated homes, livestock, tank filling, transfer to filters and solar chlorination, and humanitarian water projects. Perfect for off-grid photovoltaic installations requiring significant pressure and head.
