This pump can be used for water lifts of up to 440 feet.

The Slowpump can push water as high as 450 vertical feet. It runs on very little power, with or without batteries, to supply between 200 and 2600 gallons of water per day. The positive displacement vane pump mechanism is housed in forged brass, and lasts for years of all-day running. 5 micron filtration is required to protect the pump.

For PV-direct (no batteries in system) array, watts must exceed pump watts by 20% or more, and a linear current booster controller is required (page 123). The sizing chart shows the gallon per minute (GPM) output from the pump and power (Watts) consumed by the pump for various vertical lifts. (This is the lift from the water level to the top of the tank that the water is pumped to). The performance in the chart is measured at array direct voltage. The peak power voltage of typical solar modules is 17 Volts.

A battery powered system will have 15% lower flow and wattage. To estimate gallons per day delivery, multiply GPM figure by 60 and then by the peak sun hours per day in your location. Using a tracker with your solar modules will give you approximately 40%-50% more water in the summer. Slowpumps are available with 1/2 HP motors for greater lift.

NOTE: Pumps listed 12 or 24 Volts may be used with batteries or array direct. The 36PV/48B pumps can be run PV direct with a 36V array or from a 48V battery bank. For 120VAC operation order the desired pump and the Slowpump AC Option.

Warranty is one year.

SCB Pressure Booster Pumps

This pump can be used for water lifts of up to 277 feet of head.

SunPumps SCB series pressure pumps are multi-stage centrifugals designed primarily for boosting pressure from surface water as long as the water supply is above or no more than 3' below the level of the pump.

They are ideal pumps for home pressure systems, sprinkler systems or inline booster pumps.

SunPumps SCB series pressure pumps are very high quality, maintenance-free, DC pumps specifically designed for standalone water delivery in remote locations to be powered from batteries.

Allow 2 weeks for delivery.

Flowlight Booster Pump

This pump can be used for water lifts of up to 20 feet.

The Flowlight Booster Pumps provide "town pressure" for home water supplies where 12, 24 or 48 volt power is available. They have a longer life and greater flow rate than Flojet and Shurflo booster pumps and they use less than ½ the energy consumed by an AC jet pump running on an inverter.

The Flowlight Booster pump will be damaged if it runs dry or is used for pumping rusty or dirty water, so order a filter and dry run switch. To make installation and service easy, flexible hose connectors with ¾" threaded adapters are included. A minimum 40 gallon pressure tank is required for all Flowlight booster pump installations (available locally from a pump supplier).

The standard Flowlight model has the highest flow. Use only where suction lift is less than 10 feet.

The low flow model has a higher pressure capacity and should be used where suction lift is greater than 10 feet or where suction pipe is less than 1" inside diameter. Maximum suction lift is 20 feet at sea level for low flow model.

Use the 115 VAC pump where DC wiring is not feasible, like long wire runs. It has similar high efficiency and low starting surge. It can run on less than a 500 watt inverter.

Dimensions: 016-05" in length.

1-year warranty.

Shurflo 2088 Pressure Pumps

This pump can be used for water lifts of up to 100 feet.

These positive displacement diaphragm pumps make excellent household pressure pumps if you need less flow than the booster pumps on the previous page deliver. The Shurflo 2088 pumps up to 3.6 gallons per minute, are designed for continuous duty operation with addition of optional heat sink, and they can be run dry without harm. They have a built-in pressure switch and ½" male pipe thread ports for easy connection to common plumbing fittings.

Home pressurization installation requires a pre-charged water tank. For general water pumping, this pump can self prime to 10 feet and lift water up 100 feet. The 120 volt AC version can run on a 200 watt inverter and can be 1000 feet from the inverter using 12 gauge wire.

Dimensions: 4.45" x 12.4" x 5".
