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.
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 permanent magnet 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 (5-10 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.
Construction
- Cast iron body
- Brass cylinder and valve seats
- Leather cup piston seals
- Neoprene valve seals
- Oil-bath crankcase
- Gear (timing) belt drive on PV models
- Standard V-belt on B models
- Pressure relief valve
- Permanent Magnet DC Motor
- Surge tank included (not in photo)
Suction Capacity
- 25 vertical feet (7.6 m) at sea level. Subtract 1 foot for every 1000 ft. elevation (1 m for every 1,000 m). Suction capacity may be further limited by intake pipe friction. Intake piping should be minimum 1” (3010, 3020 models) or minimum 1 1/4” (3040). For best reliability, place the pump as close to the water source as possible.
System Requirements
- Solar-Direct Systems: Chart indicates power (w) 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)
Voltages Available:
- 12, 24, 48 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
Fittings
- Intake: 1 1/4” female pipe thread
- Outlet: 1” female pipe thread
