Lorentz PS2-4000 CS-F42-10-1 Surface Solar Pump 57m³/h 20m Centrifugal with Controller

Product Description

The Lorentz PS2-4000 CS-F42-10-1 Surface Solar Pump is a photovoltaic pumping system with very high flow, designed to move large volumes of water efficiently and with low maintenance. It integrates the PS2-4000 controller with MPPT tracking, a 4.0 kW ECDRIVE brushless motor, and the CS-F42-10-1 centrifugal head, capable of delivering up to 57 m³/h with 20 m of head. It is the ideal choice for large-scale irrigation, transfers between tanks, pond filling, or supply with extensive networks when solar energy is available.

Main Features

• Hydraulic performance: flow up to 57 m³/h and head up to 20 m with a stable centrifugal curve.
• PS2-4000 controller with MPPT, optimal operating window with Vmp > 238 V and maximum input voltage 375 V.
• ECDRIVE 4000 motor (4.0 kW) with high efficiency, 900–3,300 rpm, max current 14 A; maintenance-free.
• Integrated protections: reverse polarity, overload, overtemperature; inputs for dry well/level probes and remote control.
• Protection ratings: controller IP68, motor IPX4; ambient temperature −40…50 °C; water up to 70 °C.
• Robust construction in AISI 304 stainless steels/alloys; very high hydraulic efficiency.

Advantages or Benefits

• More water per watt: the MPPT extracts the maximum from the PV array in the mornings, evenings, or under cloud cover.
• Simplified installation: “ready to use” system with safety logics and clearly identified terminals.
• Professional reliability: brushless motor, premium materials, and active protections for long service life.
• Low OPEX: no fuel, minimal maintenance, and automatic operation by solar radiation.
• Scalability: easy adaptation of the photovoltaic array and hydraulics to flow and pressure requirements.

Purpose or Applications

Aimed at agricultural irrigation for medium/large farms (drip, micro-sprinkler, and low-medium pressure networks), long-distance transfers, pond filling, and supply with large-diameter pipes in surface solar installations. As with any surface pump, the suction must be properly sized (diameter, losses, foot valve, and suction height) to meet NPSH and avoid cavitation.

Technical Specifications

Compatibilities

Operates with photovoltaic arrays that meet Vmp > 238 V and do not exceed 375 V at the controller input. Integrates inputs for float switches/level probes, dry well protection, and remote control. Compatible with irrigation networks, check valves, filters, and collectors sized to the project’s flow and pressure. Suitable for off-grid pumping, transfer, and supply systems with solar energy.

The Lorentz PS2-4000 CS-F42-10-1 Surface Solar Pump combines high flow, intelligent control, and durability for professional projects that demand sustained performance with solar energy.
