Lorentz PS 150 Boost-125 Surface Solar Pump System

Lorentz PS 150 Boost-125 Surface Solar Pump System are high-quality products designed for higher pressure, low flow clean water boost applications. Boost pumps are typically used to pressurize water supplies. PS boost pumps provide high water pressures economically, without pollution, anywhere.

Please note: Lorentz has announced that LORENTZ solar panels must now be used with all Lorentz solar pumping systems.

  • Solar-operated surface vane type pump
  • Max lift up to 90 m
  • Max flow rate 0.48 m³/h
  • Simple installation
  • High reliability and life expectation
  • Cost efficient pumping
  • Wetted materials: stainless steel, brass, rubber, plastic.

LORENTZ PS150 Boost provides city water pressure, anywhere. It has been a standard in home renewable energy systems since 1986. It is economical for domestic water supply, drip irrigation, and water purification. Use solar-electric power to provide 250 to 10,000 liters per day from shallow water sources. PS150 Boost can push water as high as 140 m.

For 12 V to 24 V systems (1-2 solar modules or batteries in series) uses only one and the same motor and controller for solar direct or battery systems. Same flow at 12 V or 24 V.

LORENTZ PS150 Boost is not submersible but can draw water from shallow wells, springs, cisterns, tanks, ponds, rivers, and streams and push it through miles of pipeline. Slow pumping minimizes the size and cost of the solar array-battery system, wire, and piping.

LORENTZ PS150 Boost is more powerful, quieter, and much more durable than plastic RV/Marine pumps. It is less expensive than submersible DC pumps. Wearing parts typically lasts 5 to 10 years. Overall life expectancy is 15 to 20 years.


  • Drinking water supply
  • Water purification and filtration
