Zuwa pump flexible impeller

prusaprinters

<p>These are two models of a flexible impeller replacement for a ZUWA liquid pump, original part was neoprene or some kind of rubber but I think TPU should hold enough to do the job. The client said he did a cold test, no water, I'll make an update for how much it did hold up eventually. I made 2 versions, one just a drop in replacement and another one that uses the metal bushing to secure itself better to the pump axle.</p>
