Can you please help me with that? my pump knowledge is very limited,
first of all, 30 liter is a bit small for 20 liter batches. you'll need at least 35 liter vessel.
25 liter of wort, pre boil
+-5 kg of malt + same amount of absorbed water
about the pump, as long as you have good seal between the two vessels, march 809 or equivalent should be fine.
