Anyone else use a Lanphan wipe-film disto unit?
We keep having issues with the residue pump/port getting clogged. We thought maybe it was getting too cold and therefore thickening so we added heat tape set at 215°C around the arms leading to each discharge pump/valve. Still getting clogs but only on the residue side. Today I was running ethanol through the system to clean it after distilling, I had the feed @ 20 rpm, wipers @ 200 rpm, and the discharge @ 40 rpm. The residue discharge pump wasn’t moving at all. Took a heat gun too it then manually turned it forwards and backwards until it was loose and could spin normally. Even after this I had to run the pump @ 180 rpm to get even the slightest bit of flow. Ran it like this for 2.5 hours with no change. Still not flowing like normal, and the ethanol was still coming out dirty.
Wondering if it’s actually a pump issue. Anyone else have this problem using this system? Planning on just taking the whole pump apart next. Any advice is much appreciated!
