30l per minute ...

is not a thing of the pump. The crank, so the crank. But which is used to doing what they should. I had made my barrel fuel decant into canisters. Went Ruck Zuck. Shortcoming of the matter is that all wiggles like a lamb's tail while cranking. To be precise, the part which is drained into the barrel is to high a little unstable. But let dissolve. For the price, the whole Prima and therefore receives 5 stars.
