Dankoff Solaram Surface Pump

Price on request:

The Dankoff Solaram Surface Pump draws water from a shallow well, spring, pond, river, or tank. It can push water uphill and over long distances for home, village, irrigation or livestock uses.



It can use power directly from a photovoltaic array to fill a storage tank.



Uses less power than any other pump in its range, starts pumping in low light conditions.


Reduces power system cost by 25-75% compared to centrifugal or AC pumps


Rugged and Reliable

Proven design with a 20-year life expectancy

Simple to Maintain
Dry Run-tolerant
High lift and Flow


Suction Capacity

7.6m at sea level. Subtract 1m for every 1000m elevation. Suction capacity may be further limited by intake pipe friction or gases in water. For best reliability, place the pump as close to the water source as possible.

Power System Requirements

  • Solar (PV) array: Chart indicates power (W) required at the pump. For solar array-direct (non-battery) systems, the rated power of the PV array must exceed the pump watts by 25% or more
  • 120 V models: Use 10 x 12 V or 5 x 24 V modules in series
  • Linear Current Booster (pump controller) is required to facilitate starting and to prevent stalling in low-light
  • Solar tracker: Optional, to increase daily yield (typically 30%)



  • 31.2 mm Foor Valve (item #DSP-11044) if the pump is placed higher than the water source
  • Float Switch (Item #DSP-11003) for remote shut-off of the pump when the tank fills
  • Diaphragm and Oil Kit (Item #DSP-08503): Supplies for regular preventive maintenance
  • Long-term Parts Kit: (Item #DSP-08504) Three Diaphragm and Oil Kits, plus a gear belt and motor brush
