Lorentz PU200 C-SJ3-9 Solar Submersible Pump 3.3 m³/h 35m Centrifugal

Product Description

The Lorentz PU200 C-SJ3-9 Solar Submersible Pump is a professional submersible unit (Pump Unit) designed for 4” wells. It combines the high-efficiency ECDRIVE 200-C motor with the PE C-SJ3-9 centrifugal hydraulic body made of AISI 304 stainless steel and incorporates a check valve to protect the discharge line. This version is supplied without controller, making it ideal for integration with an existing Lorentz PS2-200 controller or for configuring a custom solar system. With performance of up to 3.3 m³/h and 35 m (when used with the appropriate controller), it offers an excellent balance between flow rate, head, durability, and low maintenance.

Main Features

• Pump unit (PU) with ECDRIVE 200-C brushless motor, water-filled, IP68 sealed, and maintenance-free.
• PE C-SJ3-9 centrifugal hydraulics in AISI 304 with integrated check valve.
• Design performance (with PS2-200): 3.3 m³/h flow rate and 35 m maximum head.
• Reference efficiency of the set (with PS2-200): controller up to 98%, motor up to 92%, hydraulics ≈ 53%.
• Compact format for 4” wells, silent operation, and high reliability for continuous operation in clean water.

Advantages or Benefits

• Integration flexibility: renew only the submersible part or design a custom system with the controller of your choice.
• Minimal operating cost thanks to the brushless motor and corrosion-resistant stainless steel materials.
• Hydraulic safety due to the integrated check valve that prevents backflow and water hammer.
• Lorentz modular architecture: allows separate replacement of hydraulics, motor, or controller, reducing downtime.
• Stable performance over a wide working range, maximizing water pumped per available solar kWh.

Purpose or Applications

Supply for off-grid homes, tank filling, transfers, and gravity or low-pressure irrigation. Recommended when medium flow is required with moderate heads in standard 4” boreholes.

Technical Specifications

Compatibilities

Direct compatibility with Lorentz PS2-200 Controller and with the PE C-SJ3-9 head (included in this unit). Supports dry well sensors, float switches, and remote control integration via the PS2 controller. For the PV generator, configure strings that respect the PS2-200 window (Vmp/Voc and Isc within limits).

The Lorentz PU200 C-SJ3-9 Solar Submersible Pump is the perfect modular choice for medium-flow solar pumping systems: efficient, reliable, and ready to integrate into your installation with maximum performance.
