Add the motor drive option and you have automatic fresh water delivery. The 12v motor can be powered by just a battery (car or marine type), or in combination with ONE solar panel or small wind generator for indefinite regular pumping, as well as 110v inverter/utility power using a 12 volt converter. The gear motor is a high quality Dayton - 1/5 horsepower. The motor draws 120 watts (10 amps at 12 volts) during the completed stroke cycle. The pump stroke setting is adjustable, however to optimize motor current draw and flow rate the following table lists the recommended settings. All moving parts in the gear motor assembly are operated entirely in roller bearings for an extremely long lasting mechanism.

1/5 hp with model 100 pump cylinder:

Maximum Total Head	Flow Rate GPM	Pump Stroke Setting
240 feet (104 psi)	1.5	5.8"
160 feet (69 psi)	2.0	6.9"
126 feet (54 psi)	2.0	6.9"
92 feet (40 psi)	2.0	6.9"
76 feet (33 psi)	2.0	6.9"

1/5 hp with model 125 pump cylinder:

Maximum Total Head	Flow Rate GPM	Pump Stroke Setting
200 feet (86 psi)	1.6	3.5"
150 feet (65 psi)	2.1	4.6"
123 feet (53 psi)	2.6	5.8"
103 feet (45 psi)	3.1	6.9"

Notes on calculations:
1. 100 feet of head equals 43.4 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 = 100/43.4 x 30 = 69 feet of head. Total head = 80 + 69 = 149 feet of total head. From the chart, see the next highest head of 160 feet.

The motor drive easily bolts-on the pump body in place of the handle. This arrangement can serve as a very practical water delivery method for remote cabins, livestock watering, etc. or emergency water during extended power outages. The motor drive option speeds water delivery, but can also be changed back to manual in just a few minutes, adding to the pump's versatility under any condition. An ideal, easy solution for fresh water during power emergencies or for greater independence.

12 volt Motor Option Assembly

100% CNC machined in a U.S. aerospace facility.
12 volt drive 1/5 HP motor unit. The picture on the left with cover removed shows gear-motor cam action. The assembly 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. The picture on the right shows an on/off switch and safety fuse. The motor housing is made of quality stainless steel and designed for rugged outdoor conditions. We can advise you on how to best utilize the motor drive for your particular situation using a 12v battery, solar power or other alternatives. Comes with a full one year warranty.
