Solar Water Pumping - Pressurizing Pumps

Use DC or AC power to pressurize water. Provides 3-4.5 Gallons per Minute (10-17 lpm) at pressure as high as 65 PSI (4.5 kg/sq. cm) from shallow water sources.

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.

A booster pump is far more cost effective than an elevated tank, providing pressure equivalent to over 100 feet (30m) of elevation.
This DC pump uses one third to one half the energy of a conventional AC pump, and eliminates the high starting surges that push inverters to the limit.
It is more powerful, quieter, and much more durable than plastic RV/Marine pumps. Wear-ing 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.

"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

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

This pump CANNOT tolerate dirt. Water must be filtered clear.

Warranty

1 year against defects in materials and workmanship

Dimensions

Length 16.5 in (42 cm)

Weight 15 lb (7 kg)
Flexible hose ends have 3/4-in. male pipe thread

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

Accessories

Intake Strainer/Foot Valve with fine monel metal screen, stops course debris
Inline Filter (10-inch) uses standard drinking water cartridges
Intake Filter/Foot Valve (30-inch) 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 & Shut-Off Valves, & Tank Tee (manifold)
Dry Run Switch prevents battery drain and pump damage if water source
runs dry
