The Motorized Simple Pump
"Can I buy a hand pump now, and then buy the motor later?"
Yes. You can buy a DC Motor Extension, and install it yourself. This page shows the motor options: 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.
"I need the power requirements for the motor."
For the Linear Bearing Link Drive at 100 foot static, pumping into an ambient tank....
For the Scotch Yoke drive at 100 foot static, pumping into an ambient tank....
"Will the motor be damaged I pump the water down below pump cylinder?"
Yes. When pumping air, the seals will become dry and start to wear. In the extreme, the piston could even start scratching into the precision-machined pump cylinder, rendering it, well, no longer precision-made. If you think this possibility may be of concern in your well, let us know when you ask for a quote.
"I’d like to use solar power."
Our 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.
Benefits of using batteries rather than direct connection with linear current booster...
Running the Simple Pump motor on AC
Whatever 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 converter 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 converter. The converter must be able to deal with the amperage draw spike from the motor 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.
"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.
