Made in the U.S.A.!

Since 1986, the Dankoff Flowlight Booster Pump has been the standard for providing city water pressure in conjunction with home renewable energy systems. Economical for domestic water supply, drip irrigation, and water purification, Flowlight booster pumps are far more cost effective than an elevated tank, providing pressure equivalent to over 100 feet (30m) of elevation.

Flowlight Booster Pump Advantages

• Easy to Install
• Uses one third to one half the energy of a conventional AC pump
• Eliminates high starting surges.
• More powerful, quieter, and much more durable than plastic RV/Marine pumps.
• Wearing parts are replaceable, and typically last 5 to 10 years. Overall life expectancy is 15 to 20 years.

Important Note:  This pump cannot tolerate dirt; water must be filtered clear

Choice of Capacity

• Standard Model for highest flow
• Low speed model (DC only) has higher pressure capacity, and is best when:
• Suction lift greater than 10 feet
• Intake pipe smaller than 1” size
• Extra-quiet operation is desirable

Choice of Voltage

• 12, 24 or 48 V DC
• 115 V AC (low surge PM motor minimizes inverter and wire size)

Construction & Features

• 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 Requirements

• Battery-based power system (12 or 24 V) or AC (minimum 300 W 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 Accessories

• Intake strainer/foot valve with fine Monel metal screen, stops coarse debris
• Inline filter (10”) uses standard drinking water cartridges
• Intake filter/foot valve (30”) replaces Intake Strainer and Inline
• Filter with a single unit, best for lowering into a shallow well
• Spare filter cartridges (5 or 10 micron spun fiber)
• Easy Installation Kit includes: pressure switch, pressure gauge, check, drain and shut-off valves and 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” (120 cm) or larger well casing, suspended by rope. If casing is smaller than 10”, request “adapting elbows” instead of flex hoses.

*The 2920-48 as it was known before 2012 is now the 2930-48.  Beginning in 2012, the 2920-48 will be a slightly lower volume pump. This change was made by Dankoff in order to provide a more cost effective standard speed 48 volt pump.  If you are calling for parts for a 2920-48 pump, please be sure to have the manufacture date (from the model number label) or the purchase date available.
