Koenders LD8 | Price: $180
When you have plenty of depth and require a long horizontal run, the LD8 can pump up to 2 gal. per min. With a PVC outer casing, only 3 moving parts and brass check valves, the LD8 is virtually maintenance free. Only 6 1/4" dia. x 60" long and able to fit down wells, it requires 6 ft. of water depth and must be vertically submerged. The plastic and stainless steel construction is kept buoyant in its operating position by a sealed cavity. You simply anchor it to the bottom (with about 80 lbs. of weight, it gets buoyant when filled with air), and attach the hoses to the windmill. It can also be hooked up to an existing compressor. The water pump features a 3 3/4" enlarged filler hole for faster filling. The water intake is protected by a galvanized screen to prevent debris from getting into the pump. A new secondary float releases the air pressure, creating a faster cycle time. |
