Once the idea was developed, to build a skimmer equipped with a Archimedes screw pump but able to separate part of the recovered water, we start manufacturing of the prototype.
Although our final aim is to manufacture a robust pump capable of working with any type of fluid, and being stainless steel the material that responds to such requirements, we decided to make a first prototype using the technique of selective laser sintering of nylon powder.
In this way we built the first pump with a very fragile material, so that if it passed the test we would have guarantees of adjustment and operation to proceed with the very superior investment represented by the metallic prototype.
The technology used responded very well to expectations and not only. We got a prototype that geometrically validated our design but it was also a functional prototype with which we could verify the hydraulic behavour of the pump.
