Lorentz PU1800 CS-F4-6 Surface Solar Pump 8.5 m³/h 50 m Centrifugal
Modelo: 10-010350 PU1800 CS-F4-6, 1 1/4"- Sku: LOREBOM011
- Vendor: Lorentz
Specifications
Product description
The Lorentz PU1800 CS-F4-6 Surface Solar Pump is the pumping unit (ECDRIVE 1800 motor + CS-F4-6 centrifugal head) designed to integrate with an external controller. It maintains the same hydraulic performance—8.5 m³/h and 50 m head—as the system version, but is supplied without controller for those who already have Lorentz electronics or require replacement of the mechanical part.
Main features
- Maximum flow rate 8.5 m³/h and head up to 50 m with CS-F4-6 centrifugal hydraulics.
- BLDC ECDRIVE 1800 motor, nominal power 1.7 kW, high efficiency, and minimal maintenance.
- Premium AL/AISI 304 materials and robust design for intensive use.
- Water temperature up to 70 °C; suitable for demanding surface applications.
- Dimensions and construction optimized for easy integration into existing frames or bases.
Advantages or benefits
- Economical option when a compatible controller is already available: only the hydraulic/mechanical part is replaced.
- Maximum service continuity in operations that require fast and reliable replacement.
- Efficiency and durability of the brushless motor, reducing downtime and maintenance costs.
- Capable of working with your preferred control strategy (PS2-1800), maintaining flow rate and head.
Purpose or applications
Designed for agricultural irrigation, tank filling, water transfer, and commercial use on farms with daily operation. Very useful as a replacement for an existing PS2 when the controller is operational and only the pump unit needs to be replaced.

Compatibilities
Direct compatibility with the Lorentz PS2-1800 Controller (required for operation), including inputs for dry run protection, solar sensor, and remote control. Compatible accessories: float switches/level probes, foot valves, and filters sized to the flow rate; does not include wiring, protections, or controller.
The Lorentz PU1800 CS-F4-6 Surface Solar Pump is the right choice when you need to replace the mechanical part while keeping your PS2 controller, ensuring the same hydraulic performance with reliability and low maintenance.
