The Motorized Simple Pump

"Can I buy a lever-arm pump now, and then buy the motor 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.

"I need the power requirements for the motor."

For the Linear Bearing Link Drive at 100 foot static, pumping into an ambient tank....

12VDC
16 amps peak
25 amp fuse
10-11 amps average draw

24VDC
8 amps peak
15 amp fuse
5-6 amps average draw

For the Scotch Yoke drive at 100 foot static, pumping into an ambient tank....

12VDC
18 amps peak
25 amp fuse
11-12 amps average draw

24VDC
9 amps peak
15 amp fuse
6-7amps average draw

"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 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...

  • Not limited to sunlight periods of the day for pump operation.
  • Stored power in the batteries allows operation over multiple days when sunlight is less than ideal.
  • Batteries handle the amperage draw spike better than the 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.

If you are interested in using a windmill physically powering the pump, see here...
