Lorentz PS2-4000 CS-F8-8 Surface Solar Pump 12m³/h 70m Centrifugal with Controller

Product Description

The Lorentz PS2-4000 CS-F8-8 Surface Solar Pump is a high-pressure photovoltaic pumping system designed to move large volumes of water in surface installations with maximum reliability. It integrates a controller with MPPT tracking, a 4.0 kW ECDRIVE brushless motor, and the CS-F8-8 centrifugal head, a combination that allows it to reach up to 12 m³/h and 70 m of head. Designed for agricultural irrigation, long-distance transfers, and demanding residential applications, its electronics optimize the available solar energy and protect the pump against adverse conditions.

Main Features

• Hydraulic performance: flow rate up to 12 m³/h and head up to 70 m with a stable centrifugal curve.
• PS2-4000 controller with MPPT, optimal operating range with Vmp > 238 V and max. input 375 V.
• ECDRIVE 4000 motor (4.0 kW), 900–3,300 rpm, max. current 14 A; high efficiency and maintenance-free.
• Integrated protections: reverse polarity, overload, and overtemperature; inputs for dry well/shutdown probes and remote control.
• Protection ratings: controller IP68, motor IPX4; ambient temperature −40…50 °C; water up to 70 °C.
• Outstanding efficiencies: electronics up to 98%, motor up to 92%, and hydraulics up to 60% for more water per watt.

Advantages or Benefits

• More output with the same PV array: the integrated MPPT maximizes flow in the mornings, evenings, and cloudy days.
• Professional reliability: brushless motor, stainless materials, and active protection extend service life.
• Simple installation: integrated terminals and safety logics reduce assembly and commissioning times.
• Stable pressure to cover sprinkler, microsprinkler, or drip irrigation networks at medium-high pressure.
• Low maintenance and minimal operating cost, ideal for operations with limited personnel.

Purpose or Applications

Aimed at agricultural irrigation of medium and large farms, transfers between tanks or reservoirs, filling ponds at high elevation, supplying farms, and residential/commercial applications requiring high pressure. As a surface pump, it is critical to correctly size the suction (diameter, friction losses, and suction height) to meet NPSH and avoid cavitation.

Technical Specifications

Compatibilities

Works with photovoltaic arrays that comply with Vmp > 238 V and do not exceed 375 V input to the controller. Allows integration with level probes, dry well switches, check valves, filters, and hydraulic networks adapted to the design flow and pressure. Suitable for irrigation, transfer, supply, and off-grid or self-consumption solar energy applications.

The Lorentz PS2-4000 CS-F8-8 Surface Solar Pump combines power, high pressure, and intelligent control to deliver water efficiently and reliably where the electrical grid does not reach.
