Air powered diaphragm pumps

I use the line that came with the press originally with the Oberdorfer, which is a high pressure line. But it's pretty easy to remove from pump, then I'd just use the milk hose for both inlet and outlet to transfer.

Filtered today, and it didn't want to pump very fast. Barely kept up with the evaporator for awhile. Not sure if there is an obstruction inside or what. I'll have to try pumping hot water when I break the press down again.

I have had to tear mine down and use hot water to get the sugar build up out of the check valves.
