Specifications
Product Description
The Lorentz PU150 C-SJ5-8 Submersible Solar Pump is a compact and efficient pump unit designed for medium flow applications with moderate heads in 4" boreholes. It combines the centrifugal hydraulic body PE C-SJ5-8 — made of AISI 304 stainless steel and featuring an integrated check valve — with a brushless, water-lubricated, IP68 ECDRIVE submersible motor. It offers performance of up to 4.6 m³/h and 20 m head, making it a reliable solution for gravity or low-pressure irrigation, tank filling, and water transfer using photovoltaic energy. This version is PU (does not include controller), ready to operate with Lorentz controllers that provide MPPT, electrical protections, and automation via probes and float switches.
Main Features
- Maximum flow 4.6 m³/h and maximum head 20 m (4" wells).
- Centrifugal hydraulics PE C-SJ5-8 with integrated check valve; 1.5” threaded outlet.
- ECDRIVE brushless motor, IP68, water-lubricated; quiet operation and low maintenance.
- Robust construction in AISI 304 stainless steel for all parts in contact with water.
- Lorentz modular architecture: original spare parts, easy assembly, and fast service.
- Optimal for photovoltaic systems: high efficiency and stable flow rate.
Advantages or Benefits
- Reliability and durability thanks to stainless materials and brushless motor.
- Installation protection by the integrated check valve, which prevents backflow and water hammer.
- Low consumption and excellent performance with solar energy, reducing operating costs.
- Scalable: by adding a Lorentz controller, MPPT, protections, and level-based automation are enabled.
- Ideal as a replacement pump unit in existing systems or as the basis for a new system.
Purpose or Applications
Recommended for gravity or low-pressure irrigation in orchards, meadows, and gardens, tank and pond filling, watering troughs, and water transfer on agricultural or livestock farms. Its performance is optimal in 4" wells when medium flow and moderate head are required, both in off-grid solar installations and in hybrid configurations with grid or generator support.

Compatibilities
As a PU version, it requires an external controller. It is compatible with Lorentz PS2-150 controllers, which add MPPT, protections, and probe control. When integrated with PS2-150, size the PV generator to meet: aggregate Vmp > 17 V and total Voc ≤ ~50 V DC; ensure the Isc of the photovoltaic array is within the controller's range. Compatible spare parts and accessories: C-SJ series (PE C-SJ5-8 head), ECDRIVE motors, and Lorentz level/float sensors.
The Lorentz PU150 C-SJ5-8 provides efficiency, robustness, and ease of integration for building professional submersible solar pump systems with medium flow and moderate head.
