1 out of 10 MFI lines I get are fully or partially clogged. I want to make a closed system pump that will cycle hydrochloric acid through the line, maybe using compressed air as the pump like in a blast cabinet.

Now I'm running .30 welding wire through lines and then compressed air, multiple times, and while that works, it is extremely slow and painful.

I envision clear tubing at each end connected to a pump. I could even see putting some glass bead in the system to burnish the walls.

Any ideas?
