Lorentz PS1800C-SJ8-5 Centrifugal Submersible Water Pump

• Lift up to 2 - 25 m
• Maximum flow rate up to 16 m³/hour "Centrifugal "
• Cost efficient pumping
• Maintenance free
• High reliability and life expectancy

LORENTZ was established in Hamburg, Germany and has been a quality designer and manufacture of Solar Pumps since 1993. Through the innovative electronic controlling, outstanding manufacturing quality and a simple design, Lorentz have managed to reduce the high cost of solar water pumping. Their submersible helical rotor pumps consist of only two parts, Lorentz's brushless motors are water filled and maintenance free, while the electronics are NOT inside the submerged motor but easily accessible on the surface.
