Food Safe Pumps?

I was looking into what it would take to make my hydro lettuce into a certified organic product. Apparently, all of the hydro system has to be constructed with only "food safe" materials. They make food safe pond liners, and I have seen organic hydro lettuce grown in a raft system. But I think the aeration is done with an air pump. I can't seem to find food safe water pumps in the size I need. They make small ones for beer brewing and solar collectors, but they are too small. I would like a food safe mag-drive 300-600gph pump, or even something larger like a sump pump would be fine in a bigger system. But I don't think such a product exists???

Marine animals are sensitive to chemicals, so probably water pumps for large aquariums will be good enough. I've seen 450 gph ones.

The "Mondi" pumps distributed by C.A.P. are food safe I think. I know they are oil free. Also look at U.S. Plastic, they are real good at identifying which products are FDA food safe.
