Flowlight Booster Pump Specification Sheet

The Dankoff 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.
A booster pump is far more cost effective than an
elevated tank, providing pressure equivalent to over
100 feet (30 m) of elevation.
It uses one third to one half the energy of a
conventional AC pump, and eliminates high starting
surges.
It is 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.
Our complete instruction manual and easy
installation kit make this pump simple for anyone to
install and service, with no previous experience.
Suction Capacity
• Low speed model 20 vertical feet (6 m) at sea level
• Standard model 10 Feet (3 m) at sea level
• Subtract 1 ft. for every 1,000 ft. altitude (1 m for
every 1,000 m) for both versions.
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” 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) 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, others (inquire)
• 115 V 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 (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)
