Air-powered kills it for me, Wayne.

Wayne,
I forgot to say that it needs to be self-priming.

I may have made an ASSumption ass of myself as I have a pump that meets my
requirements perfectly and I *assumed* that it is a gear-pump. I need to
break it down to find out. I bought it used, online.


Gear pumps can be self priming to a certain extent when new but
generally should be at least wet with oil at the start. But when they
have some wear they will have to be primed. I can think of only a few
true self priming pumps capable of priming such a thick liquid.
However most are not really suitable to your use. One that does come
to mind as a possibility is a air powered diaphragm pump. I believe
you can get them in other than air powered as well. Try starting at
page 314 on McMasters web site.
