Lorentz PE C-SJ12-4 Hydraulic Body for submersible solar pump

Product Description

The Lorentz PE C-SJ12-4 Hydraulic Body is the original Lorentz centrifugal head for high-flow submersible solar pumps in 4" wells. Its AISI 304 stainless steel construction and integrated check valve ensure mechanical reliability, minimal head loss, and protection of the water column. With a performance of up to 20 m³/h and 18 m head, it is the safe choice for maintenance, replacement, or upgrading of solar pumping systems seeking a balance between flow and pressure with maximum durability.

Main Features

• Maximum flow rate of 20 m³/h and maximum head of 18 m.
• Centrifugal design with integrated check valve to prevent backflow.
• Reference maximum hydraulic efficiency around 58 %.
• Premium materials: AISI 304 stainless steel in parts in contact with water.
• For 4" wells; recommended water temperature ≤ 50 °C.
• Approximate head weight: ≈ 6.0 kg (reference from datasheet).

Advantages or Benefits

• Greater hydraulic safety thanks to the integrated check valve.
• Corrosion resistance and extended service life in demanding environments.
• Stable performance that enables rapid filling of tanks and reservoirs.
• Original Lorentz spare part: perfect fit and easy maintenance.
• Interchangeable in the Lorentz modular architecture with ECDRIVE motors.

Purpose or Applications

Ideal for transfers, gravity or low-pressure irrigation, tank filling, and supplying agricultural or livestock operations that require high flow in 4" boreholes.

Technical Specifications

Compatibilities

Compatible with Lorentz ECDRIVE 1200/1800 motors and with sets from the series: PU1800 C-SJ12-4 (pump unit) and PS2-1800 C-SJ12-4 (system with controller). Use as a direct replacement in equipment from the same family.

The Lorentz PE C-SJ12-4 Hydraulic Body combines performance, robustness, and easy integration to keep your submersible solar pump operating at the highest level.
