Dankoff SlowPump 1303 – 24V

The 1303 booster pump can draw water from shallow wells, springs, cisterns, tanks, ponds, rivers and streams, and push it as high as 240 vertical feet and through miles (kilometers) of pipeline. Slow pumping minimizes the size and cost of the solar array, wire and piping. SlowPumps are less expensive than submersible DC pumps, and made in a much wider range of sizes. Wearing parts typically last 5 to 10 years. Overall life expectancy is 15 to 20 years.

Suction Capacity
20 vertical feet (6 m) at sea level – subtract 1 ft.. for every 1,000 ft. altitude (1 m for every 1,000 m). Pump should be placed as low as possible and gravity fed water is best.  Filters, angled joints, and small diameter pipe will all impact usable suction capacity.

Performance Range
20 feet of lift delivers 2.5 gpm using 65 PV watts.  Maximim of 240 feet of lift delivers 1.96 gpm using 235 PV watts.

Filtration Requirement
This pump cannot tolerate dirt. Water must be filtered clear. If water is very dirty, improve the source.

PV-Direct (non-battery) Requirements

The rated power of the PV array must exceed pump watts by 20% or more. See spec sheet for more info.

A DSP200 Controller is required to start and run in low light. Ask about availability.
