Heavy Duty Surface
Pumps - Water Pumping
Slowpump
Solar/DC Surface Pump
The Slowpump can push water as high as 450 vertical feet. It runs
on very little power, with or without batteries, to supply between
200 and 2600 gallons of water per day. The positive displacement vane
pump mechanism is housed in forged brass, and lasts for years of all-day
running. 5-micron filtration is required to protect the pump. For
PV-direct (no batteries in system) array, watts must exceed pump watts
by 20% or more, and a current booster controller is required. The
sizing chart shows the gallon per minute (GPM) output from the pump
and power (Watts) consumed by the pump for various vertical lifts.
(This is the lift from the water level to the top of the tank that
the water is pumped to). The performance in the chart is measured
at array direct voltage. The peak power voltage of typical solar modules
is 16 Volts. A battery powered system will have 15% lower flow and
wattage. To estimate gallons per day delivery, multiply GPM figure
by 60 and then by the peak sun hours per day in your location. Using
a tracker with your solar modules will give you approximately 40%-55%
more water in the summer. Slowpumps are available with 1/2 HP motors
for greater lift. NOTE: Pumps listed 12 or 24 Volts may be used with
batteries or array direct. |

Solar
Force Piston Surface Pump
The Solar Force utilizes solar electricity or battery power to draw
surface water from a shallow well, spring, pond, river or tank. It
can push water uphill and over long distances. It is also used for
domestic or irrigation pressurizing. As with all surface pumps, suction
capacity is 25 feet (subtract 1 foot for every 1000 feet elevation
above sea level). It is dirt tolerant, very long-lasting, and reliable.
This pump uses less energy per gallon of water delivered than any
pump we sell. The pump head is cast iron with a brass cylinder. 2-year
warranty. Pump is shipped in 2-3 parcels. |

Solaram
8000 Surface Pump
Solaram Surface 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, to fill a storage tank. The Solaram is
Dankoff’s most powerful surface pump. It pushes water uphill
as much as 1000 vertical feet, to supply as much as 5400 gallons per
day while using less power than any other pump in its range. The Solaram
will start pumping even in low light conditions. Using a Solaram reduces
power system cost by 25-75% compared to centrifugal or AC pumps. The
pump is rugged and reliable, easy to install and is dirt and dry run
tolerant. It has a proven design with a 20-year life expectancy. Requires
preventive maintenance every 2 years (based on full year-round use).
