Solar Force Piston
|
Use
Solar-Electric Power for water lift or pressurizing from shallow
water sources. Provides as much as 5600 Gallons per day (21,000
ltrs.) pushing as high as 230 Feet (70m) or 100 PSI (7 kg/sq.
cm)

“We
have one [Solar Force] pump that serves a community
of 30 people and visitors. It more than adequately meets
our needs.”—Brother Philip, Christ in the
Desert Monastary, Abiquiu, New Mexico
“I
want to tell you how happy I am with our Solar Force
Piston Pump. What a workhorse! Gallon for gallon, the
price of the pump is well worth it in quality and performance.”—R.S.,
Molokai, Hawaii
“Nothing
will pump more water per watt than the Solar Force—Nothing!
And, it's built like a tank. I've seen similar pumps
50 years old, still working.” —Larry Elliot,
Solar Tech, Bend, Oregon

Solar
Force Piston Pump draws water from a shallow well, spring,
pond, river or tank. It can push water uphill and over
long distances for home, village, irrigation or livestock
uses. It can use power directly from a photovoltaic array,
or from storage batteries, to fill a storage tank or to pressurize
water.
Solar
Force is . . .
- Ultra-Efficient:
Uses less power than ANY other pump in its range
- Economical:
Reduces power system cost by 25-75% compared to centrifugal
or AC pumps
- Solar-Direct
Application:
Starts pumping in low light conditions
- Pressurizing
Application: DC version is most efficient. AC version
uses a low-surge PM motor that greatly reduces starting
surge, inverter size, and wire size requirements
(when compared to conventional AC pumps).
- Rugged
and Reliable:
Proven design with a 20-year life expectancy. Simple to
maintain with common tools (2-6 yr. maintenance interval)
- Good
Tolerance for Dirt and Dry Run
- Mechanical
Drive allows engine or hand-lever backup
- Illustrated
Instruction Manual makes it easy for anyone to install
and service, with no previous experience.

Voltages
Available
- 12,
24, 48, 90 VDC
Note: PV-Direct full working voltage is typically 20% higher than
nominal (example: 29 Volts for a 24V system)
- 115V
or 230V AC, 50-60Hz

Suction
Capacity
- 25
vertical feet (7.6m) at sea level. Subtract 1 foot for every 1000
ft. elevation (1m for every 1000m). Suction capacity may be further
limited by intake pipe friction or gasses in water. Intake piping
should be minimum 1 inch (3010, 3020 models) or minimum 1 1/4
inch (3040). For best reliability, place the pump as close to
the water source as possible.

System
Requirements
- Solar-Direct
Systems: Chart indicates power (watts) required at the pump. The
rated power of the PV array must exceed this number by 20% or
more. A pump controller (linear current booster) is required for
the pump to start and run in varying light conditions. A solar
tracker may be used to increase daily yield (40-55% in summer).
- Pressurizing
Systems: Battery power system, pressure switch, and pressure tank
of minimum 60 gallon (230 l) size (captive-air tank, available
locally)
- Foot
valve (if pump is placed higher than water source)
|
|
Accessories
- Foot
Valve FV-3000 (1-1/4 inch) required if pump is placed higher than
water source
- Pressure
Switch: Heavy Duty DC rated, for pressurizing systems
- Surge
Tank: Absorbs pulsation if long piping is required between pump
outlet and tank (Included with PV models)
- Seal
& Gasket Set : Spare gaskets, rod and valve seals, two sets of
piston seals, and a belt
- Long-Term
Parts Kit: The above, plus a second belt, motor brushes, cylinder
sleeve, 2 oil changes
|
|
Fittings
- Intake:
1 1/4 inch female pipe thread
- Outlet:
1 inch female pipe thread
|
|
Accessories
- Intake
Strainer/Foot Valve with fine monel metal screen, stops course
debris
- Inline
Filter (10-inch) uses standard drinking water cartridges
- Intake
Filter/Foot Valve (30-inch) replaces Intake Strainer and Inline
Filter with a single unit, best for lowering into a shallow well
- Spare
Filter Cartridges (5 or 10 micron spun fiber)
- Easy
Installation Kit includes: Pressure Switch, Pressure Gauge, Check
, Drain & Shut-Off Valves, & Tank Tee (manifold)
- Dry
Run Switch prevents battery drain and pump damage if water source
runs dry
