Lorentz PU4000 C-SJ42-2 Submersible Solar Pump 53m³/h 18m

Product Description

The Lorentz PU4000 C-SJ42-2 Submersible Solar Pump is designed to move large volumes of water at medium head using photovoltaic energy. It integrates the brushless ECDrive 4000-C motor and the PE C-SJ42-2 centrifugal hydraulics, offering up to 53 m³/h with 18 m of lift in 6” wells. Its modular architecture allows it to be combined with the Lorentz controller that best suits the PV array and installation requirements. This PU (Pump Unit) version refers only to the pump unit; controller not included, providing flexibility for new projects or replacements in existing systems.

Main Features

• Two-stage centrifugal hydraulics optimized for 53 m³/h and 18 m head.
• ECDrive 4000-C brushless motor, water-filled and IP68: high efficiency, low maintenance, and long service life.
• Construction in AISI 304 stainless steel and technical polymers for corrosion resistance and intensive service.
• Integrated non-return valve (NRV) to protect the water column and prevent backflow.
• Format for 6” wells, easy installation, and accessible servicing.
• Modularity: compatible with Lorentz controllers from the PS2 family/other equivalents. Controller not included.

Advantages or Benefits

• High flow at medium head: ideal for gravity irrigation, rapid tank filling, and transfers between reservoirs.
• Reduced total cost of ownership: water-cooled brushless motor, no brushes or critical maintenance.
• Design flexibility: the installer selects the controller according to the PV array, wiring, and available protections.
• Greater reliability and service life due to stainless materials, integrated NRV, and separate electronics.
• Quiet and efficient operation in professional solar systems.

Purpose or Applications

Targeted at agricultural operations, livestock, ponds, and light industrial uses that require moving large volumes of water at intermediate heads. Also suitable for recirculation systems, elevated tank supply, and autonomous solar pumping solutions on farms or remote sites.

Technical Specifications

Compatibilities

For operation, a compatible Lorentz controller (for example, PS2-4000) and a photovoltaic array sized to the controller’s range (Vmp/Voc and power within limits) are required. Usual accessories: level and dry well sensors, DC type II protections, submersible cable, and discharge pipe/hose suitable for the flow and line length.

Lorentz PU4000 C-SJ42-2 Submersible Solar Pump provides a robust, efficient, and modular foundation for professional solar pumping projects seeking high flow and long-term reliability.
