We currently a 1/5 HP gear motor that will actuate the pump. It is powered by a customer supplied, 12Volt dc power source. This can be an automotive or deep cycle marine battery. The gear motors are modular to our model 100 hand pump and bolts into place in less than five minutes. Since the gear motor only sees a full load on part of it's cycle, the average power consumption is about 120 watts on the 1/5 HP. With a 1/5 HP unit, and a customer's 75 watt solar module, will produce about half the run time to the charge time. A common, inexpensive, 25 watt module will produce 1 hour of pump time to 6 hours of charge time. All moving parts in the gear motor assembly are operated entirely in roller bearings for an extremely long lasting mechanism. We have been performing tests with a Wal-Mart $35 deep cycle battery. We have not been able to determine the "amp-hour" capacity of the battery, but it easily operates our pump under a full load for 4 hours at a time between charges.

Our gear motor shown in the picture has an adjustable crank linkage. The five positions allow the motor load to be optimized for the pumping depth. The delivery will vary between 3.4 and 3.1 GPM depending on total head. With 12 hours of pumping per day, this translates to between 540 and 2200 Gallons per day of pumping capacity. (See the table below for capacities.)

The Gear motor assembly is sold as a bolt on option for our existing hand pump. The housing is constructed entirely of stainless steel. The assembly replaces the existing handle assembly and bolts on in less than five minutes. The motor is fuse protected and has its own on/off switch. The mechanism is fully enclosed for outdoor installations. The customer supplies the 12-15 volt dc power source. This can be a portable battery, a vehicle parked nearby or more permanent power sources.

To the right is view of the crank mechanism. The system runs entirely in roller bearings for minimal friction and dependability.

To the left is a view of the back side with on/off switch and replaceable fuse.

Shown below is a a schematic diagram on how you can tie the Simple pump into your house pressure system. With this arrangement, the 12V pump becomes the primary pumping source by coming on at 35 psi. The AC existing pump will come on at a lower - 30 psi if the 12v cannot keep up under high demand.

Flow Capacities and Pressures

Notes:

1. 100 feet of head equals 43.3 PSI.
   
2. Example of total head calculation: The well water level is at 80 feet, the pump is at 100 feet and we want to deliver 30 psi from the pump head. 30 psi = 100/43.3 x 30 = 69 feet of head. Total head = 80 + 69 = 149 feet of total head. From the top chart, choosing the next highest head of 160 feet = 1.0 GPM.

Warranty: The gear motor assembly is warranted against defective materials and workmanship for a period of 1 year from the date of purchase. The motor load must not be exceeded and any routine maintenance recommended in the instructions must be adhered to.
