Not sure what MH is but in bigger systems magnetically coupled centrifugal pumps are used afaik.

I’ve always had a problem with peristaltic pumps. Given it’s all electrolyte, would other tech like MH be possible?

I have experience with peristaltic pumps. What issues do you mean?

Plastic tubing wears out because its continuously deformed. Also the backflow

Hmm… I use cheapass silicone tubing, 5mm ID 7mm OD and wear hasn’t been an issue. Perhaps you compress the tube too much. The tube should be held shut so that no liquid flows backwards but also not compressed so much that it wears the tubing out. Your pump should have a variable tensioner on it.
Perhaps also you don’t have enough rollers. At least one roller needs to be in full contact with the tubing (compressing) so that there is no backflow.

Not sure what applications you have for your stack, but runtime of tubes is significant when considering operational lifetime in design.
