Lorentz PU4000 CS-F42-10-1 Surface Solar Pump 57m³/h 20m Centrifugal

Product Description

The Lorentz PU4000 CS-F42-10-1 Surface Solar Pump is the pumping unit composed of the ECDRIVE 4000 motor with 4.0 kW and the CS-F42-10-1 centrifugal head. It achieves up to 57 m³/h at 20 m head, sharing the same hydraulic performance as the PS2-4000 version, but in this model the controller is not included. It is designed to be integrated with Lorentz PS2-4000 controllers or other compatible control/inverter solutions that provide MPPT, protections, and operational logic, allowing the system to be configured to the specific needs of the project.

Main Features

• Hydraulic performance: flow rate up to 57 m³/h and head up to 20 m with a stable curve for large diameters.
• Brushless ECDRIVE 4000 motor (4.0 kW), 900–3,300 rpm; high efficiency and maintenance-free.
• Robust construction in AISI 304 stainless steel and premium alloys; designed for continuous operation.
• Motor protection rating IPX4; ambient temperature range −40…50 °C; water up to 70 °C.
• High efficiencies that reduce the required size of the photovoltaic array and operating costs.

Advantages or Benefits

• Integration flexibility: allows selection of the ideal controller (PS2-4000 recommended) and the appropriate PV/automation architecture (PLC, SCADA, telemetry).
• Cost optimization: reuse existing controllers or implement advanced functions only where they add value.
• Long service life: brushless motor and stainless materials minimize downtime, wear, and maintenance.
• High flow with low-medium pressure for transfers, rapid tank filling, and extensive irrigation.

Purpose or Applications

Recommended for surface solar installations that require very high flow with customized control: agricultural operations with automation, existing irrigation networks, large volume transfers, and reservoir filling. As with any surface pump, it is critical to properly size the suction (diameter, losses, foot valve, and suction height) to meet NPSH and avoid cavitation.

Technical Specifications

Compatibilities

Requires a solar pump controller to operate (e.g., Lorentz PS2-4000). The photovoltaic array must be sized according to the electrical window of the selected controller (high working voltages and suitable input limit), respecting its voltage and current limits. Compatible with irrigation networks, check valves, filters, manifolds, and standard accessories (level probes/switches, dry well protection, remote control) properly sized to the flow and pressure of the project.

The Lorentz PU4000 CS-F42-10-1 Surface Solar Pump delivers exceptional flow with professional construction, offering total freedom to select the most suitable control and PV architecture for each installation.
