Lorentz Solar Water Pumping Systems are some of the most efficient pumping systems in the world. The unique 3-Phase motor design allows you to harness the sun for all your pumping needs. All Lorentz Pumps can be utilized with Solar direct or battery powered system operation.


  • Controlling of the pump system and monitoring of the operating states
  • Mounted at surface (no submerged electronic parts)
  • Two control inputs for well probe (dry running protection), float or pressure switches, remote control etc.
  • Protected against reverse polarity, overload
  • and high temperature
  • Flow rate up to 2.7 m3/h
  • Simple installation
  • Maintenance-free
  • High reliability and life expectancy
  • Cost-effective pumping solution


  • Drinking water supply
  • Livestock watering
  • Remote Pond management
  • Pipeline and Irrigation
  • HR Pumps
  • Helical rotor pump (positive displacement pump)
  • Two main parts only: stator and rotor, field servicable
  • Stator: geometry made of abrasion resistant rubber
  • Rotor: stainless steel, hardchrome plated, abrasion resistant
  • More resistant to damage by sand than other pump types
  • Self-cleaning

Sand and Silt Tolerance:

The pump (HR) has a higher resistance to wear from sand, clay etc. than any other pump type. In properly constructed wells the amount of particles is within the tolerance of the pump. A concentration of particles higher than 2% (by volume) may cause blockage in the pump or the drop pipe, especially at low flow rates.
Do not use the pump to clean out a dirty well.

Pump Cable and Splice:

Standard submersible cable, 3-wire + ground (total four wires). Connection to the pump is made using industry-standard splicing methods.

Drop Pipe:

G 1 1/4″ (optional: 1″ NPT) pump outlet. If water is dirty consider a smaller sized drop pipe to increase the flow velocity. This helps to exhaust solid particles and prevent accumulation in the pipe. When considering reduced pipe size, consult a pipe sizing (friction loss) chart. Pipe can be of any standard material, rigid or flexible. A torque arrestor is not required.
