INSTALLATION INSTRUCTIONS FOR THE MOTORIZED SIMPLE PUMP SYSTEM (LINEAR BEARING LINK DRIVE OPTION) LAST UPDATED: November 13, 2017 (The following instructions are very detailed, and should tell you everything you need to know. If you have questions, please phone 775-265-1220.)
When assembled and installed on the Model 125, the gear motor is capable of delivering 2.0 gallons of water per minute (GPM) from as deep as 175 feet. Installed on the Model 100, it delivers 1.3 GPM. The motor is available in two models, 12 volt and 24 volt DC. These instructions cover both versions.
RECOMMENDED OPERATING ENVIRONMENT AND APPLICATIONS AMBIENT TEMPERATURE DC motors operating in ambient temperatures above 100˚F lose operating efficiency -- the hotter the ambient temperature, the less efficient. If the temperature at the planned site regularly peaks above 100˚F, we recommend operation of the motor in shade.

By contrast, any Simple Pump provides water with a pulsed delivery, and therefore varying pressure, making the task of regulating flow to the pressure tank more difficult.
PROFESSIONAL HELP? If this is more complex than you planned, there are alternatives. Anyone with NABCEP (North American Board of Energy Practitioners) certification, and experience configuring off-grid systems, is almost certainly qualified to help. However, while all NABCEP-certified professionals must learn about off-grid systems, most pursue grid-tie solar systems -- a very different field.
SECTION 3: PREPARING YOUR EXISTING PUMP Your Simple Hand Pump should already be installed and pumping water without any binding and with an overall smooth operation prior to attempting to install this gear motor. You should confirm that your pump is delivering at least one gallon of water with approximately 25 strokes with the lever handle system (model 100L).

Using the 3/16" Allen wrench, loosen the pinch bolt and the 3 mounting bolts on the split flange enough to pull the pump head (including riser tube) up out of the well. While holding the pump head by the riser tube, seat the safety tool securely in the split flange.

Use a channel lock to remove the riser tube and pump head. This allows access to the 3/4" stainless rod. Do not remove the stainless nipple. Disconnect the 3/4" stainless rod from the topmost sucker rod (left). The stainless rod shipped with this Motorized Pump with Linear Bearing Link Drive is longer than the lever arm stainless rod just removed.

Reinstall the pump head and riser tube. Secure it firmly on the stainless nipple that is attached to the topmost drop pipe. Lift the riser tube (and pump head), and then remove the safety tool. Lower the riser tube so that at least 6 inches of riser tube are below the split flange on the cap.
SECTION 4: INSTALLATION Lower the Linear Bearing Link Drive Mechanism (LBLD) so that the stainless rod is inserted into 3 openings. ‣ Orientation: When you lower the LBLD onto the stainless rod, the electric terminals are on the top side. ‣...

Rotate the Linear Bearing Link Drive Mechanism around the pump head until the holes for the four mounting bolts are aligned. There is 1/4" of space between the bearing housing and the top of the rod gland when the holes are aligned. The rod gland is the topmost exposed component on the pump head.

Attach your 12V or 24V power source to the terminal strip. Attach the cover to the LBLD mechanism. Use your 9/64" Allen wrench for the (6) 8-32 SS SHCS that attached the cover the the mechanism’s mounting plate. Diagram below shows how the cover fits onto the mounting plate.
(if 12VDC version) or 15 amp ATO/ATC automotive style fuse (if 24VDC version). Using a higher amperage fuse will overheat the motor and damage the gears. The motor normally operates at around 100-110º F. p a g e 13...
Remove the motor mechanism and stroke the pump rod by hand. It should require about 40 lbs. of lifting effort for each 100 feet of static water level depth. If the effort is any more than this, remove the pump head and try again to determine if the problem is in the head.
