Lorentz PU4000 C-SJ60-1 Submersible Solar Pump 78m³/h 10m
Modelo: 10-004771 PU4000 C-SJ60-1, Rp 4", UL- Sku: LOREBOM068
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU4000 C-SJ60-1 Submersible Solar Pump is designed to move very high volumes of water with low head in 6” wells. It integrates a brushless ECDrive motor filled with water and the C-SJ60-1 centrifugal hydraulic stage, offering up to 78 m³/h with 10 m of lift. Its modular architecture reduces maintenance and allows components to be replaced separately. This PU (Pump Unit) version is the pump unit without control electronics; it requires a suitable external Lorentz controller. Controller not included.
Main Features
- Centrifugal hydraulic C-SJ60-1 optimized for extreme flow of 78 m³/h and 10 m head.
- ECDrive 4000-C brushless motor, water-filled, IP68, and high efficiency.
- Construction in AISI 304 stainless steel and technical polymers for long service life.
- Integrated non-return valve (NRV) that protects the water column.
- Compact format for 6” wells; easy installation and service.
Advantages or Benefits
- Professional solution for rapid tank filling, transfers, and gravity irrigation.
- Low total cost of ownership: brushless motor, minimal maintenance, and stable performance.
- Modularity: you can replace only the hydraulic or the motor if necessary.
- Quiet and efficient operation in solar pumping systems.
Purpose or Applications
Ideal for agriculture with high flow demand, livestock, fish farms, pond recirculation, and light industrial uses where volume is prioritized over pressure.
