Specification: Motor: Permanent magnet DC brushless motor Recommended working lift: 0~40m Recommended solar panel: 24 volt, 500~800 watts Max lift: 50m flow: 2000L/H Power 500W Operating voltage range: 18~45v Rotational speed: 3500~4000rpm Power unit: single screw driven by single motor Dimension: Max diameter: 89mm Outlet port diameter: 32mm Net weight: 5.7kg Gross weight: 6.5kg Installation 1. This pump is a solar powered water pump, 36v is ideal input voltage. The solar panels' power should be 1.5~2 times bigger than the pump. 2 or 3 pcs 12 volts batteries connected in series also can be power source. 2. Connect the pump to solar panels directly, if the total length of the cable between pump and solar panel is longer than 100ft, we strongly recommend 9 or 8AWG wire. 3. Safety rope or wire is very important for deep well pumps, because the safety rope or cable will be the only way to retrieve the pump from the bottom of the well, we recommend a good stainless steel cable rather than rope. 4. If your solar panel kit is not powerful enough and you don't want to add more, a couple of 12v batteries is a good option, they can help to hold the input voltage above the "low voltage cut off point", however, sufficient solar panels is still the best power source. Tips: 1. Clean the pump's intake and outlet port when you think the flow rate is not as high as before. 2. Make a "sleeve" for the pump if you want use it in impure water. 3. Notice the water level in the well, sucks in air will damage the pump's motor.
