A friend of mine is a distributor for Iwaki pumps here in AZ. I was talking with him about the possiblity of getting the 20rz in a dc motor, but one would have to order 200 pumps to be able to get one.
If someone were to place this large order (i.e. me), would there be enough interest in a 12v or 24v version of this pump? I don't know any bulk pricing at this point, but I think it might be a decent business venture (due to the wide release of the Storm G4) if there was enough demand.
Let me know what you guys think.
