Simple Pump. Motorized pump. Ideal for solar.Adding a motor now or later. Capabilities.The Motorized Simple PumpCan I buy a lever-arm pump now, and then buy the DC Motor extension later?Yes. You can buy the DC Motor Extension later, and install it yourself. We have an entire page that discusses this: http://www.simplepump.com/OUR-PUMPS/Motorized.html. You can also read about one of our customers who runs a Simple Pump directly from his solar panel: http://www.simplepump.com/WHY-SIMPLE-PUMP/Hermit-Pad.html. Will the motor be damaged I pump the water down below pump cylinder?Absolutely, YES. When pumping air, after the seals disintegrate (which doesn't take an awful long time, when dry), the piston starts etching scratches into the precision-machined pump cylinder, rendering it, well, no longer precision-made. If you think this may be of specific concern in your well, let us know when you ask for a quote. I’d like to use solar powerOur DC Motor is designed to be frugal in its use of power and is ideal for use with solar power. Provided the site is arranged so that the PV panels have good year-round line of site to the sun, only one or two panels are required, along with batteries and other components. (Capacity of panels and other components needed must be determined by a solar specialist.) Can I run the motor directly from a solar panel, i.e. without batteries?Yes, the 12VDC Simple Pump motor can run directly off of solar panels but there are caveats....
For these reasons, the preferred system layout is solar panel(s) charging (2) 6VDC batteries in series via a charge controller....with the Simple Pump running off the batteries. Further benefits of using batteries...
Running motor on ACWhatever the source of electricity, we recommend using batteries between the source and the motor. So if you want to use AC, we recommend using the AC to charge batteries and using those to drive the motor. If you run direct, the inverter you use must have an output no less than 20 amps 12VDC. This amperage, higher than you might have expected, is due to uncertainty over internal inefficiencies with the inverter. The inverter must be able to deal with the amperage draw spike from the 105ME/GM during the work portion of the operating cycle. Batteries handle this draw spike with no problem. Batteries, of course, also the advantage of giving you reserve power when there is an outage. If you run out of power --- Hand-operation and motor operation are easily and quickly interchangeable, giving you even greater convenience and security for your water supply. The Simple Pump is actually unique in this regard. Does the motor have any circuit boards that would be susceptible to an EMP?There are no circuit boards in our 105ME/GM motor assembly. Just a rocker on/off switch and a 25 amp glass fuse. No EMP vulnerability. Can I drive my pump with wind power?Yes, you can. There is, howover, a "but"... You can use any source of 12 volts DC to drive the motor. The most commonly implemented is to use batteries and to have some way of charging the batteries - usually solar. Alternatively, this could be a windmill driving a generator that charges batteries. If you are interested in using a windmill physically powering the pump, see here...
