Lorentz PU4000 CS-F8-8 Surface Solar Pump 12m³/h 70m Centrifugal

Product Description

The Lorentz PU4000 CS-F8-8 Surface Solar Pump is the pumping unit — ECDRIVE 4000 motor of 4.0 kW plus CS-F8-8 centrifugal head — for surface photovoltaic projects that require high flow and high pressure. It shares the same hydraulic performance as the PS2-4000 version (up to 12 m³/h and 70 m head), 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 manage MPPT, protections, and system operation logic.

Main Features

• Hydraulic performance: up to 12 m³/h and 70 m with optimized CS-F8-8 centrifugal curve.
• ECDRIVE 4000 motor (4.0 kW), 900–3,300 rpm; high nominal current and high efficiency.
• Robust construction in AISI 304 stainless steel and high-quality alloys; maintenance-free design.
• Motor protection rating IPX4; ambient temperature −40…50 °C; water up to 70 °C.
• Outstanding efficiencies: motor up to 92% and hydraulics up to 60% to reduce PV field size.

Advantages or Benefits

• Integration flexibility: the installer chooses the ideal controller (PS2-4000 recommended) and configures MPPT, level inputs, and telemetry according to the project.
• Cost optimization: allows reuse of existing controllers or implementation of advanced automation (PLC, SCADA, etc.).
• Long service life: brushless motor and stainless materials minimize downtime and maintenance.
• Stable performance for sprinkler/microsprinkler irrigation at medium-high pressure, transfers, and supply with long pipelines.

Purpose or Applications

Suitable for surface solar installations that require custom system control: agricultural operations with automation, existing irrigation networks, elevated tanks, or long-distance transfers. As with any surface pump, the suction design (diameter, losses, foot valve, suction height) must be carefully considered 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 (for example, optimal high Vmp in medium-high voltage configurations), respecting voltage and current limits. Compatible with level probes/switches, dry well protection, check valves, filters, and hydraulic networks for irrigation, transfer, or supply.

The Lorentz PU4000 CS-F8-8 Surface Solar Pump offers the hydraulic power of the 4000 series with the freedom to select the control and PV architecture that best suits your professional project.
