DC Water Pumps
|
Pump formulas: PSI = Feet of Head x 0.434 or Feet of lift = PSI x 2.31
DC Water Pumps
These positive displacement diaphragm pumps with permanent
magnet motors are more efficient than standard AC water pumps and can run dry
without damage. Provide regular water pressure for home. Pump from very shallow
wells, cisterns, creeks, ponds, tanks. Use for garden, livestock, fire
protection, camping, etc. Add a standard captive air tank to minimize pump
cycling. Power pump from a battery or use 1 or 2 solar modules directly to pump
water when the sun shines. A pump controller, such as P630, will increase
performance. Motor must be kept dry or motor will be damaged and void warranty.
The 120 volt model will work on a 200 watt inverter and can be used with small
wire (14 gauge for Flojet, 12 gauge for SHURflo) for long distances (over
1000).

Flojet Diaphragm Pumps
2 piston diaphragm pump and built-in pressure switch 40-60
psi. A standard pressure switch can be used instead of the built-in switch to
operate at 20-40 psi for less energy used and longer pump life. Motor draws more
amps at higher pressures. Rated 2 gpm open flow, 1.3 gpm at 60 psi, 115 lift,
up to 8 self priming with idea conditions. 120 degrees F, 160 degree pumps
(model 2130) are available on special order with higher pressure and
slightly less flow rate. Okay to use 24 volt model on 12
volts at reduced power and flow. 3Ό x 9 |

heating compost toilets, floors or other closed loop, low flow applications. Can
operate directly from solar module without battery or controls and pump
proportional to the suns brightness.

DC pumps have an advantage over AC pumps. They are more
efficient and can be independent of power line power. This advanced design
is brushless, highly efficient, magnetic coupled drive, no maintenance, no
shaft and shaft seal leakage, no fan, 250F degree temperature maximum, 175 psi maximum,
vertical or horizontal mounting, 1/2" NPT Male connection. PV
models are used solar direct. B12 models are connected to a 12 volt battery.
Okay to use the PV model on a battery but it will run slower. Do not run a
battery model PV direct. The voltage will be to high for it.
A common AC
to DC wall adapter power supply is used for AC operation. Use a fast blow
fuse (3AG-312.xxx) with battery models. PV watts will vary depending on
available sunlight and if using Glycol. Glycol takes more energy to pump, so
use the higher PV watts. Keep the voltage under 20 volts for the 12 volt PV
pumps.
Long life expectancy - some might last 10 - 20 years. Indoor or protection use only.
Common uses:
5PV for two 4X10 solar heating panel or one panel if using
Glycol antifreeze.
10PV for three 4x10 solar heating panels or two 4x10 panels if using Glycol
antifreeze.
10B for Radiant Floor Heating, use 1 pump per standard size zone.
20B12 will need a 30 watt PV module for flat plate solar collectors and 40
watt PV module for vacuum solar collectors.

Solar Slowpumps
info sheet available
The Dankoff Solar Slowpump is less expensive than submersible
DC pumps, and made in a wide range of sizes. Any of the Slowpump models can
operate directly off of solar panels or batteries. They can be operated at half
of their rated voltage which provides half the rated flow and requires half the
required wattage for a given lift. This means that your Slowpump installations
are expandable and very flexible. We also have AC Slowpump for installations
where efficiency is paramount but the power comes from the utility company, a
generator or an inverter. The Slowpump can also be used to pressurize in
applications where the lift requirements are higher than our FLowlight Booster
pump can do. Wearing parts typically last 5 to 10 years. Overall life expectancy
is 15-20 years. All Slowpumps require filtration of up to 10 microns and must
not run dry.
|
 |
APPLICATIONS
Use Solar-Electric Power to provide 200-2,600 Gallons per Day (750-10,000 ltrs.)
from shallow water sources. Slowpump can lift water as high as 450 vertical feet
(137m).
|
|
DC Booster Pump
Rotary vane positive displacement pump is more quiet than
diaphragm pumps and has a smooth flow with higher GPM. Pressure output is equal
to 100 high storage tank. An inlet filter must be used to protect precision
pump parts. A foot valve should be use to keep pump primed. Pump will be damage
if ran dry. Designed for use with a pressure tank. Maximum lift from storage
tank to pump is 10. Use low flow model if total dynamic head is greater than 50
psi or existing suction pipe is less than 1 or you expect frequent filter
clogging due to dirty water. 15-20 year life with 5-10 year overhauls.
Pump shown with installation kit.
Uses .6 watt-hours per gallon at 30 psi, and 1.1 watt-hours
per gallon at 65 psi.
