Highly reliable 36V DC solar submersible brushless well pump system, which allows you to pump water from wells as deep as 66 feet (20m) using included 24W solar panel. It supplys as much as 180 gallons (660 liters) per day.
* Its patented sealed piston mechanism uses less than 24 watts of power requiring a smaller, less costly array. (Most solar deep-well sumbersible pumps use centrifugal impellers, requiring much more power.)
* Its patented brushless mechanism is the biggest breakthrough since traditional solar diaphragm motor pump, and eliminates the timely repairs and replacements of the latter.
* Reliable and maintenance-free brushless mechanism in solar pump has no failure-prone carbon brush and shaft seal, ensuring robust long service life of solar pump. 
* Robust and reliable - It features full stainless steel construction.
* No batteries required. It runs efficiently in low sunlight and hazy days.
* It fits a wide range of needs: deep wells, drinking water, stock watering and drip irrigation, etc.
* Automatic operation for years - minimal maintenance is required. Special construction allows dry operation for hours.
* Tolerates sediment and sand in the water supply - can be used in rivers and streams.
* Low borehole drilling costs ---- a diameter of 3-1/4" (8.0cm) is sufficient.
* Solar pump must not be operated directly with any batteries.
* Operating temperature of the pump: +1^oC  -  + 50^oC. 
* Operating temperature of the driving controller: -10^oC  -  + 50^oC.
* Solar power supply: max 24 W, input voltage with load 33V.
* Maximum current: 0.8A ; minimum current 0.1A.
* Free accessories include driving controller, lifting rope, water pipe, foam filter, silicone tube, O-ring, main spring, hexagonal key (3/8" and 1/8") and resin-free oil.
* Operating instructions: English, German, Chinese, French, Spanish.
* Note: 24W, 35V solar panels already included.
