Years ago I have seen a model made from brass for sale in a swedish parts and whatnot's catalogue, it's was'nt expensive either.. (tho the term is relative, I know)... but it was small, and elegant. just need hoses and there u go.

Thank you for the information! No, our

rampump won't win a price for external beauty, but

it's the cost price that makes it beautiful. The video says it would cost only 20 euros, but in Guatemala we discovered that it took only one bag of

cement to make it: 5 euros. So it is affordable, even for the poorest to irrigate their land.

We strive for similar cost-reductions in other designs as well, and with that we can use some help. Please, visit our website for information.
