  • 1 x complete set of spare o-ring seals


The product's lifecycle is 1 - 5 years. A warranty is provided of 5 years if the product is purchased from a distributor or 1 year if purchased directly from Futurepump's factory.

Manufacturer Specified Performance Parameters

The manufacturer specifies the following performance targets: At shallow heads, the Futurepump SF2 solar water pump can deliver up to 1 l/s, which is 3,600 l/hr (120W).

  • Inlet side vertical suction limit: 7 meters
  • Maximum total vertical lift: 15 meters
  • Horizontal discharge: 500m+

Vetted Performance Status

VeraSol tested the Futurepump SF2 at the Schatz Energy Research Center in July 2019 and found that with 80 W from solar panels, a maximum head of 13.3 m is achieved. Other performance parameters were also tested and a product quality inspection was performed which found the SF2 to be of 'Good' quality (the highest on their scale). The Global LEAP Awards also tested the Futurepump SF2 in 2019, their results included that the SF2 can pump a total volume per day of 9.2 m3/day on a sunny, high irradiance day.


No known safety hazards are related to this product.

Complementary Technical Systems

The Futurepump SF2 Datasheet lists several accessories that complement the pump. The Futurepump SF2 solar water pump is compatible with:

  • Direct irrigation using a hosepipe
  • Sprinklers (available from Futurepump)
  • Drip
  • Overhead tanks
