I like the one pint per stroke. Stainless type material?
No, I would imagine it is merely steel. Its suggested use is for pumping petroleum type liquids.
I will go with the RV hand water pumps if and when I get to it. This one just looks cooler and, well, delivers a pint per pump!
I guess if I want aesthetics I will have to fabricate my own out of Stainless some how. Course that will end up costing more than a real beer engine... So that defeats the purpose of making a homemade one.
