Lorentz PU4000 CS-F16-3 Surface Solar Pump 22 m³/h 40 m Centrifugal

Product Description

The Lorentz PU4000 CS-F16-3 Surface Solar Pump is the pumping unit composed of the ECDRIVE 4000 motor with 4.0 kW and the CS-F16-3 centrifugal head. It delivers up to 22 m³/h and 40 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 manage MPPT, protections, and operational logic, allowing the system to be configured exactly to the project's requirements.

Main Features

• Hydraulic performance: up to 22 m³/h and 40 m with stable CS-F16-3 centrifugal curve (max. efficiency 63%).
• Brushless ECDRIVE 4000 motor (4.0 kW), 900–3,300 rpm; max. current 14 A; high efficiency and maintenance-free.
• Robust construction in AISI 304 stainless steel and premium alloys; designed for continuous operation.
• Environment: motor IPX4; ambient temperature −40…50 °C; water up to 70 °C.
• Compact unit for surface mounting; easy access to hydraulic and electrical connections.

Advantages or Benefits

• Integration flexibility: the installer chooses the ideal controller (PS2-4000 recommended) and the PV/telemetry architecture (PLC, SCADA, monitoring) according to the project.
• Cost optimization: allows reuse of existing controllers or adding only advanced functions where they add value.
• Long service life: brushless motor and stainless materials reduce downtime and maintenance.
• Stable performance for low-medium pressure irrigation, medium-distance transfers, and tank filling.

Purpose or Applications

Suitable for surface solar installations with custom control: automated agricultural operations, existing irrigation networks, transfers between tanks/ponds, or supply with extensive piping. As with any surface pump, carefully 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 (respecting its voltage and current limits). Compatible with standard pumping accessories: level probes/switches, dry well protection, check valves, filters, and properly sized hydraulic networks for irrigation or transfer.

The Lorentz PU4000 CS-F16-3 Surface Solar Pump provides the hydraulic power of the 4000 series with complete freedom to select the most suitable control and PV architecture for each professional installation.
