| Item code | Brand name | Model number |
| DAKFL-2920-24 | Dankoff Solar Pumps | Booster Pump 2920-24 |
These pumps are not for use in PV-direct applications. You must either use a battery or AC power to power the pump.**As well, the images show the whole system together. The price above is for the pump only. See addons below for the Install Kit, Filter Assembly etc - all sold separately.

"Over the last five years, we've found our Flowlight pump to perform impressively. If installed properly and filtered, they are very faithful pumps." --- J.T., Nemia Valley, British Columbia, Canada "Our (Flowlight Booster Pump) has had 2 1/2 years of daily use. I have no complaints at all. It works really fine." --- G.O., Willow, Alaska "It's a delight to be weaned from the generator." ---C.H., Coulterville, California |

The Flowlight Booster Pump provides city water pressure, anywhere. It
has been a standard in home renewable energy systems since 1986. It
is economical for domestic water supply, drip irrigation, and water
purification.Specifications

Capacity
* Suction Lift: Low Speed Model
20 vertical feet (6 m); Standard Model 10 Feet (3 m) at sea level -- subtract
1 ft. for every 1000 ft. altitude (1 m for every 1000 m)
Note: Suction capacity may be further limited by intake pipe friction. Excessive
suction causes cavitation (vapor bubbles) creating noise and
excessive wear. Intake piping should be 1 inch or larger. Pump should be mounted
as close to the water source as possible.
Choice of Capacity
* Standard Model for highest flow
* Low Speed Model (DC only) is best if:
- Suction lift greater is than 10 feet
- Intake pipe is smaller than 1-inch size
- Extra-quiet operation is desired
Choice of Voltage
* 12 or 24 Volt DC,
others (inquire)
* 115 Volt AC (low surge PM motor minimizes inverter and wire size)
Construction
* Rotary vane pump
mechanism (pulsation-free)
* Solid forged brass pump body with carbon-graphite and stainless steel working
parts
* NSF® approved for drinking water
* Handles sea water and dissolved minerals
* Survives most freezes
* Permanent magnet, ball bearing DC motor, thermally protected
* Clear flexible hoses and pressure relief valve included
Additional Needs
* Battery-based power
system (12V or 24V) or AC (minimum 300 watt inverter)
* Pressure Tank, captive air type. Minimum size: 40 gallon (150 l). Larger is
better, to reduce cycling and increase reserve capacity.
Available locally.
* Foot valve (if pump is placed
higher than water source)
Filtration Requirement
* The Flowlight Booster Pump CANNOT tolerate dirt. Water must be filtered <10 microns.
Accessories (**These are NOT included -please see Add-ons below or your Sales Rep)
* Intake
Strainer/Foot Valve with fine monel metal screen, stops course debris
* Inline cartridge holder (10-inch) uses standard drinking
water cartridges
* 10" filter cartridges (2 pack ) for above cartridge holder.
* Intake Filter/Foot Valve (30-inch) replaces Intake Strainer
and Inline Filter (10 micron) with a single unit, best for lowering into a shallow
well
* Spare 30" 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
Installation
* Pump may be mounted horizontally or vertically.
* Pump must not be submerged
* It may be placed inside a 6-inch (120 cm) or larger well casing, suspended
by a rope. If casing is smaller than 10 inches, request "adapting elbows"
instead of flex hoses
Dimensions
* Length 16.5 in (42 cm)
* Weight 15 lb (7 kg)
* Flexible hose ends have 3/4-in. male pipe thread
Warranty
* 1 year against defects in materials and workmanship. Use of pump without 10 micron or less filter will void warranty.
