Model LJ 108S / LJ208D / LJ 308-T - Micropumps



Small, simple, robust and inexpensive solar powered pumps for the micro water distribution in agriculture, homes, animal water supply or irrigation are important components in decentralized and renewable powered water infrastructure.This solar submersible pump has many useful applications with solar energy in industry and household. It is an ideal combination of water and sun – environmentally friendly. It saves primary energy and physical efforts like pumping with manpower in order to obtain or distribute water. It works according to the principle: The more sunlight, the more water is pumped. Runs even in hazy weather. It is a very effective application for family gardens or small rural areas with the solar drip system.

  • A 12 W Solar panel for a depth up to 10 meters (appr. 30 ft) Type LJ108 is needed
  • A 24 W solar panel for a transport level up to 20 meters (appr. 60 ft), Type LJ208 is needed
  • A 36 W solar panel for a transport level up to 30 meters (appr. 90 ft), Type LJ308 is needed.

The pumps have a low maintenance requirement and perform automatic operation for years. The special construction allows drying operation for hours. They are robust and reliable which results into low costs for the whole system. With a low borehole cost a diameter of 6,0 cm is sufficient. The pumps are also very suitable for usage in a 2' borehole.
