This configuration raises the overall reliability and longevity of the system. Transfer pumps include an
integrated pressure switch. The switch turns the transfer pump on and off, according to a target
pressure. If you are able to use the Simple Pump to pump into pressure, we STRONGLY suggest that you
wire in a pressure switch to control the ON/OFF state of the system (See Section 10 for details). If the
pump is not controlled in this way and is left on, it could exceed the allowed pressure and potentially
damage both the pressure tank and/or the Simple Pump gear motor. If you have any questions or
concerns about your application and the limits explained above, please call us at 877-492-8711,
extension 6.
UNSUPPORTED APPLICATIONS
Operating the Motorized System (LBLDWR Option) in certain configurations voids its warranty.
‣Exceeding the rated total dynamic head limit of the Motorized System.
‣Not performing normal maintenance events
SOLAR POWER SOURCE
Choose a location as close to the well as possible and practical, this helps eliminate any voltage drop
between components (i.e loss of available power). Keep in mind the cables provided for the connection
from the solar panels to the control box are 25’ in length. (Custom lengths are also available, however
the gauge of the wire may need to increase depending on the length required.)
Also keep in mind that the solar panels will need to be facing south and should be positioned such that
they are not shaded by any other structures, plants, trees, or even the pump itself.
Batteries
You will need two 12v batteries, Group 27 or 31 Deep Cycle (from almost any auto parts store) and
minimum 100 amp-hour rating.
Lead acid will be the least expensive, probably around $125.00 each on sale. AGM will be about three
times what the lead acid cost but will provide longer run time.
Battery storage is left to you to determine, following is guidance on what to think about when picking
an enclosure. The batteries need to be kept clean and dry at all times, out of the rain, snow, ice, and
direct sunlight, to increase longevity. The battery enclosure should be high enough off the ground or
sealed to avoid rain runoff and snow accumulation (if applicable). This system requires that you place
the batteries as close to the well head as possible in an enclosure meeting the description above. The
cables provided to connect the batteries to the control box are 4’ in length. The cables provided to
connect from the control box to the drive system are 12’ in length. We recommend that both the
batteries and the control box are stored in the same enclosure/building/location.
