K.H uses a big Tellarini from this range for his processing:
http://www.tellarini.com/inglese/prodotti2b_ing.htmI have a couple of them, a little one ENM25 (53lpm) to transfer oil and a brand new big one ENM40 (149lpm) which is "in the collection" but I've not found a use for yet.
They really are beautiful pumps, as they self-prime, are reversible, are ever so quiet in operation and not closed impeller like a lot of pumps of that flow (so less likely to block).
I'm trying to work out if I would be willing to part with the bigger one, since I'm not using it - but you know what it's like, part with it then want to use it for something like building a big processor.
If you want pressure for running a venturi/eductor well then the multi-stage Calpedas are the bees knees - the MHXM range. Stainless lovelyness and great for pressure, however closed impeller so can block up with lumps in the oil.
