- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU4000 C-SJ30-2 Submersible Solar Pump is a professional pump unit composed of a Lorentz ECDRIVE submersible motor and a C-SJ30-2 centrifugal hydraulic body, designed to deliver a very high flow rate with low head. With a capacity of up to 44 m³/h and 22 m of lift, it is ideal for rapid filling of ponds, tanks, and transfers in agricultural or livestock operations. This version does not include a controller, and is intended to be integrated with Lorentz controllers from the same family for operation with photovoltaic energy.
Main Features
- Maximum flow rate of 44 m³/h and maximum head of 22 m for 6" wells.
- C-SJ30-2 centrifugal hydraulics in AISI 304 stainless steel with integrated check valve.
- ECDRIVE 4000 submersible, brushless motor, water-lubricated, with IP68 protection rating.
- Lorentz modular design: easy maintenance and availability of original spare parts.
- Silent operation and high hydraulic efficiency for moving large volumes with solar energy.
- PU version (Pump Unit): does not include controller; ready to pair with the appropriate control system.
Advantages or Benefits
- Maximum flow performance for gravity irrigation, transfers, and low-pressure tank refilling.
- Superior durability thanks to stainless materials and IP68 sealed motor design.
- Protection of the water column through an integrated check valve that prevents backflow.
- Modular architecture that simplifies installation, facilitates servicing, and reduces downtime.
- Compatibility with Lorentz solar controllers that add MPPT, protections, and automation with probes and float switches.
Purpose or Applications
The PU4000 C-SJ30-2 is perfect for solar pumping projects in agriculture, livestock, pond/tank filling, transfers between tanks, supply for operations, and gravity or low-pressure sprinkler irrigation. It is also suitable as a replacement for the hydraulic/motor unit in existing systems that already have a compatible controller.

Compatibilities
This unit does not include a controller. It is compatible with Lorentz controllers from the corresponding range (for example, PS2-4000) and with standard level sensors/inputs on the Lorentz platform (well probe, float switches, dry-run protection). As a reference for an equivalent set, this hydraulic is the same as that used in systems with the PS2-4000 C-SJ30-2 controller. If you already have a suitable Lorentz controller, the PU4000 is the correct option to replace the pump unit.
The Lorentz PU4000 C-SJ30-2 offers an optimal balance between high flow rate, reliability, and stainless construction, enabling the creation of high-performance submersible solar pump systems to move large volumes of water with photovoltaic energy.
