Iwaki pump for Calcium Reactor

[hipertec]

My Iwaki external pump went out. It was an old model, so I was wondering what would be a good Iwaki or Little Giant Pump for my Calcium Reactor?
Would I get a pressure rated external pump?
Thanks for your help!

If you were happy with your reactor before, probably a pump with similiar specs to your previous one.

I'm running a Mag3 on a DIY reactor but had some issues at the start with leaks fr the pump cover so wouldn't recommend them.
