3020-12PV Solar Force® Piston Pump

requires 12VDC PV-Direct power

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 photo-voltaic array, or from storage batteries, to fill a storage tank or to pressurize water. Uses 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)

Features

• Ultra-Efficient: Uses less power than ANY other pump in its range
• Economical: Reduces power system cost by 2575% 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 20year life expectancy. Simple to maintain with common tools (5-10 yr. maintenance interval)
• Good Tolerance for dirt and dry run
• Mechanical Drive allows engine or hand-lever backup

The illustrated instruction manual makes it easy for anyone to install and service, with no previous experience.

Recommendations

"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, Bonanza, Oregon

Total Lift = Vertical Distance from surface of the water source to the pipe outlet or top of storage tank.

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. Intake piping should be minimum 1inch. For best reliability, place the pump as close to the water source as possible.

Construction

• Cast iron body
• Brass cylinder and valve seats
• Leather cup piston seals
• Neoprene valve seals
• Oil-bath crankcase with special oil included
• Gear (timing) belt drive on PV models
• Standard V-belt on B models
• Pressure relief valve
• Permanent Magnet DC Motor

System Requirements

• Solar-Direct Systems: Chart indicates power (watts) required at the pump. The rated power of a 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 liter) size (captive-air tank, available locally)
• Intake fittings, use 1 1/4inch female pipe thread
• Outlet fittings, use 1inch female pipe thread

Accessories

• Foot Valve: 1 1/4inch (required if pump is placed higher than water source)
• Easy Installation Kit: (for pressurizing applications) Heavy duty pressure switch, pressure gauge, check, drain and shut-off valves, and tank tee (manifold)
• 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 and Belt Kit: 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

Dimensions: 22 X 13 X 16inch high (56 X 33 X 41 cm), total height 26inch (60 cm) with Surge Tank. Max. weight 80 lbs (36 kg) Shipped in 2 or 3 parcels
