Dirty-water Pumps “Dirty-water” source – your perspective as system designer Typical sources: Ponds, Lakes, Rivers SunCentric SolarForce Piston Pump Solaram

SunCentric – High Flow, Low Lift Output: 5 – 70 GPM Total Dynamic Head (TDH): Up to 90 ft. Suction Capacity: 10 vertical feet at sea level. Subtract 1ft. for every 1000ft. altitude Notes: Does not require filtration – tolerant of dirt; NOT for pressurized applications; no routine maintenance required Warranty: 2 years against defects in materials and workmanship

SolarForce Piston Pump - High Volume Pressure Output: 5 – 9 GPM Total Dynamic Head (TDH): Up to 230 ft. or 100 PSI Suction Capacity:  25 vertical feet at sea level.  Subtract 1ft. for every 1000ft. altitude Notes:  20-year life expectancy with 5-10 year maintenance intervals; Tolerant of dirt and dry run Warranty: 2 years against defects in materials and workmanship

Solaram - High Lift/High Pressure Output: 2.5 – 9 GPM Total Dynamic Head (TDH): Up to 1000 ft. or 433psi Suction Capacity: 25 vertical feet at sea level.  Subtract 1 ft. for every 1,000 ft. altitude Notes:  Great for high-lift applications; 20 year life expectancy; Tolerant of dirt and dry run Warranty: 1 year against defects in materials and workmanship

Clean-Water Pumps “Clean-water” source – your perspective as system designer Typical sources: Holding Tanks, Shallow well SlowPump Flowlight Booster

SlowPump – High Lift, Low Flow Output:  0.2 – 6.2 GPM Max Total Dynamic Head (TDH):  560 ft.  Suction Capacity: 20 vertical feet at sea level.  Subtract 1ft. for every 1000ft. Altitude Notes:  MUST be filtered clean (reference spec. sheet); 15 – 20 year life expectancy Warranty: 1 year against defects in materials and workmanship

Flowlight Booster – Low Volume Pressure Output:  3 – 5 GPM Total Dynamic Head (TDH): 65 PSI Suction Capacity: Standard model (2920):  10 vertical feet at sea level.  Subtract 1 ft. for every 1,000 ft. altitude Low Speed model (2910): 20 vertical feet at sea level.  Subtract 1 ft. for every 1,000 ft. altitude Notes:  MUST be filtered clean (reference spec. sheet); 15 – 20 year life expectancy Warranty: 1 year against defects in materials and workmanship

Common Livestock Applications “I have a pond and want to water 200 head of cattle” Dirty water + no need for pressure = SUNCENTRIC 2. “I have submersible pump/windmill drawing water from a well, but now I want to move it from holding tank beside well all the way to my holding tank in another pasture” Clean water + just need to move water + practical size = SLOWPUMP

Livestock Applications – Cont’d 3. “A river runs through my property and I want to be able to water my cattle. I can place the pump on the river bank, but during droughts, the water level gets really low.” dirty-water + high suction lift likely = SOLARFORCE PISTON PUMP

Common Preparedness (“Prepper”) Applications “I want water for my home to be independent/off-grid. I have a well I can pump out of. What should I do?” Two-pump setup: Out of the well to holding tank PV-direct (no batteries). This stage likely not a Dankoff pump, UNLESS it is shallow well. Pump from holding tank to house with pressure, battery-based. Dankoff provides this stage: Clean Water + Need for pressure + battery-based = FLOWLIGHT BOOSTER

Preparedness (“Prepper”) Applications – Cont’d 2. “I need an efficient sump pump to pump away water from my house when it floods” Dirty Water + Need for high flow rate (GPM) = SUNCENTRIC

Common Irrigation Applications “I am putting in a rainwater catchment system and need a pump to irrigate with, using the water I collect off my roof” First key question: Are you okay with only pumping when sun is out? Or, do you want to pump at night and early morning? “Yes, that’s fine” = PV-direct  SlowPump “No, I want to pump on-demand” = battery-based  *likely Flowlight Booster Second key question: Do you want pressurized irrigation (drip tape) or open/flood irrigation? “Pressurized” = Flowlight Booster (SolarForce or Solaram if large-scale) “Open” = SlowPump (SunCentric if large-scale)
