Dankoff Solar SlowPump Model 1303-24 Dankoff Solar SlowPump Model 1303-24, 24 Volts DC The Dankoff Solar SlowPump model 1303 is available in 12 Volts DC, 24 Volts DC, 48 Volts DC and 115 Volts AC. It's maximum PSI is about 100 and the maximum suction lift is 20 feet at sea level. For every 1,000 feet of elevation, the pump loses 1 foot of suction lift. For example: If your elevation is 4,000 feet, the maximum suction lift of the pump will be 16 feet. It's always best to limit the suction lift as much as possible. By placing the pump closer to the water source, it will run more efficiently and quietly. A noisy pump can indicate that your total suction lift exceeds the pump's specifications. This pump cannot tolerate dirt. The water MUST be filtered clear. Sea water and dissolved minerals will not cause any problems. The 12V, 24V and 48V models can be powered directly with solar power.Specifications: Fittings are 1/2 inch female 5.75" x 17.375" (14.61cm x 44.14cm) Weight: 12 pounds Warranty: 1 Year Total Lift Model 1303 Feet Meters GPM PV Watts 20 6 2.50 65 40 12 2.50 80 60 18 2.44 90 80 24 2.36 110 100 30 2.33 130 120 36 2.33 140 140 42 2.27 160 160 48 2.21 180 180 54 2.11 190 200 60 2.03 220 240 72 1.96 235
