The Installation
This turned into a real saga. The first detail to consider was a
base for the pump to stand on. The SolarJack is a big mother- weighing
in at some 300+ pounds or so. We opted to pour a concrete slab that
surrounded the well casing. This slab would allow us to position
the SolarJack precisely over the mouth of the well casing. Alignment
between the polished stainless steel rod sticking up from the well
seals, and the working head of the SolarJack must be within 1/16
of an inch. The slab we poured was 4 feet wide, 6 feet long, and
16 inches thick. We used two layers of steel wire mesh as reinforcement.
We, at Electron Connection, enlisted the aid of Gene and Pat of Gene's
Pump Service in Medford, Oregon to install the pump down the well.
We needed to lower the pump piston/cylinder assembly, the 399 feet
of 2" pipe and the 399 feet of fiberglass rod into the well. The
weight of this assembly required a truck with a boom and a gas operated
pony engine.
Once the pump, pipe and rod were properly fitted and lowered down
the well, the seals and polished rod were installed at the well head.
Next the pump was positioned properly and secured to the concrete
slab with eight 3/4 inch in dia. by 3.5 inch long lead anchors and
lag screws. The job of drilling the holes in cement precisely was
difficult and redrilling was necessary on the pump base to get everything
to line up. Use a heavy drill for this job and drill the holes one
at a time. Install each mounting bolt before drilling the hole for
the next. After the pump was secured to the slab, we attached the
polished rod to the working head with the steel cable harness. The
pump was now ready to operate once it had a power source.
PHOTO OF PUMP CREW
We racked the PVs using slotted steel angle and cement piers. This
arrangement is strictly temporary. The PV are to be moved to the
roof of the pump house as soon as Don White gets it constructed.
Once the PVs were racked and wired we hooked it up and took it for
a ride. We flipped the ON switch on the SolarJack's LCB and the
motor immediately started and the pump came up to speed. About 30
strokes per minute. We waited until the pipes filled to the holding
tanks, and adjusted the counterweights as per SolarJack's instructions.
Pump Performance
The sun shines, the pump pumps+ all day long. The output of the
system is some 1,170 gallons per day. The pump is not very noisy,
we couldn't hear it from about 100 feet away. It runs without human
attention. The White's don't even have to be home to pump their
water. The sun shines and the pump pumps+ All day long+
