Product Overview

Product Details


The Lorentz PS 150 HR-04S Solar Submersible Pump is a high specifications solar powered helical DC pump specifically designed for reliable small-scale water supply from boreholes and wells and is the ideal solution for remote pumping requirements in livestock watering, irrigation and general water supply applications. Pumps feature a remote surface mounted controller and are constructed principally from AISI 304/316 stainless steel and they are engineered to the highest standards to give easy serviceability, excellent efficiency, high reliability and long life.


Pumps are fitted to ECDRIVE 150-HR-S maintenance-free water-filled brushless DC motors without integrated electronics. They should be powered by solar arrays configured to provide the input voltage required and sized at approx 120% of the rated motor power.

Speed: 600-3300 rpm Insulation Class: F Enclosure Class: IP68 CONTROLLER.

The Lorentz PS 150 HR-04S Submersible Pump utilizes the PS 150 Controller. The controller is matched for monitoring, protecting and controlling pump operation that feature:

• Protection against reverse polarity overload and over temperature.

• Integrated MPPT (Maximum Power Point T racking) for maximum solar energy conversion efficiency .

• Low voltage disconnect for battery protection.

• Control inputs for dry running protection and remote control.


Pump output curves are given at standard test conditions of 1000W/m solar irradiance and 25 C. Output will vary throughout the year depending upon prevailing irradiation levels. For estimated daily outputs at continuous pumping multiply the indicated output at the duty point by the daily irradiation given in Graph 1.

For indicative purposes factors of 1.1 can be applied for hot arid areas and 0.9 for temperate high altitude areas in East Africa. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2.

NOTE: Output estimations are strictly indicative. More accurate projections are available using manufacturers data when the exact site location and installation arrangement is defined. This information will be provided with all offers.


Pumped Liquid: Thin, clean, chemically non-aggressive liquids without solids and fibres. Maximum Liquid Temperature: +50 C

Max Ambient Temperature: +50 C

Max Immersion Depth: 250m
