Lorentz PU4000 CS-F32-20-2 Surface Solar Pump 42m³/h 30m Centrifugal

Product Description

The Lorentz PU4000 CS-F32-20-2 Surface Solar Pump is the pumping unit formed by the ECDRIVE 4000 motor of 4.0 kW and the CS-F32-20-2 centrifugal head. It offers up to 42 m³/h and 30 m of head, sharing hydraulic performance with the PS2-4000 version, but in this model the controller is not included. It is designed to be integrated with a Lorentz PS2-4000 controller or other compatible controls/inverters that provide MPPT tracking, protections, and operating logic, allowing the system to be configured exactly to the project's needs.

Main Features

• Hydraulic performance: up to 42 m³/h and 30 m with a stable centrifugal curve.
• Brushless ECDRIVE 4000 motor (4.0 kW), 900–3,300 rpm; max current 14 A; high efficiency and maintenance-free.
• High efficiencies: hydraulics up to 74 % and motor up to 92 % to reduce PV field size.
• Robust construction in AISI 304 stainless steel and premium alloys; continuous operation.
• Protections and automation available through the selected controller (level, dry well, remote, etc.).
• Environment: motor IPX4, ambient temperature −40…50 °C; water up to 70 °C.

Advantages or Benefits

• Total flexibility: the installer chooses the controller and PV architecture (MPPT, telemetry, PLC/SCADA) according to the application.
• Cost optimization: reuse existing controllers or add only the advanced functions that provide value.
• Durability: brushless motor and stainless materials minimize maintenance and downtime.
• Suitable curves for moderate pressure irrigation, medium-distance transfers, and tank filling.

Purpose or Applications

Suitable for surface solar installations that require custom control configuration: farms with automation, existing irrigation networks, transfers between ponds and elevated tanks. As with any surface pump, correctly 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 field must be sized according to the electrical window of the chosen controller (respecting maximum voltages and currents). Compatible with level probes/switches, dry well protection, check valves, filters, and hydraulic networks sized to the project's flow and pressure.

The Lorentz PU4000 CS-F32-20-2 Surface Solar Pump provides high flow, professional construction, and configuration freedom for demanding surface solar pumping projects.
