Just be sure the motor will not be submerged if the water level rises, or it will be ruined. The more you minimize suction lift, the more reliable and quiet your pump will be. Some pumps, such as the Shurflo will pull from about 5 to 8 feet at sea level. However there are no perfect pumps - 6 to 25 foot suction is the max on most. The maximum possible suction limit for even a perfect surface pump is 31 vertical feet at sea level (subtract 1 ft. MINIMIZE SUCTION LIFT to just a few feet. Note about surface pumps of all types - including Shurflo & Dankoff - that pulls water from a tank, spring, cistern, or whatever: The largest pumps generally available are 1/4 to 3 HP. Solar powered well pumps are seldom suited for large amounts of water, such as irrigating larger fields if you have AC power available. Depths over 500 feet will generally cost quite a bit more.
The well may be anywhere from a few feet to 1800 feet deep - but the deeper the well, the more expensive the system. Some older wells drilled for windmills are less than 4" (usually 2.25"), and solar submersible pumps will not fit. The most common casing size is 6", but 5" and 4" are also seen in older wells. Submersible solar pumps are generally used for pumping from wells, and are designed to fit inside the well casing in a drilled hole. ** If you are not sure about what you need, please give us a call at 8we can suggest the best products for your application, or can design the complete system for you. Some (such as the popular 12 volt Shurflo pumps) are often used for pressurizing small water systems in homes, RV's, and boats.
Flows can be small (1/2 gallon per minute or so) up to 30-40 gpm.
Some are capable of high pressure while others are intended mainly for moving large volumes at low pressure (such as moving water from a cistern to a stock watering tank). Solar pumps fall into two major categories - surface, which includes pressure, delivery, and booster pumps & submersible - primarily submersible well pumps.ĭelivery pumps are used to move water from one place to another. We also carry a complete line of accessories, hardware, and installation parts and kits. We carry solar powered water pumps (and a few AC pumps) from several manufacturers, including Grundfos (SQF), SunPumps, Dankoff, and Shurflo.
