I was able to get a couple of Iwaki pumps off E-bay for dirt cheap, I mean CHEAP!! Only problem is I have no idea of the history of these pumps. And the seller is a recycler who bought a large lot and is reselling them. No way to know what liquid these pumps pushed. I want to assume that Iwaki uses parts that will not absorb what ever fluids it is pushing, is that a safe assumption? How can I go about ensuring they are safe? I was thinking about mixing up 10 gallons and have the pump run on that for a day or two then test it. But what am I testing for since it could have been any liquid used.
