The peristaltic can go up to 2.3 litres per minute.It's a Cole-Parmer Masterflex - off ebay for less than the cost of a March pump. So it's slower, but can prime itself and even sit on a shelf above all the kettles.The tubing isn't much worse than others options. You would use silicone, or Tygon. It's variable speed, I can also use it for racking wine and stuff if I really wanted to.
The magnetic pumps I grabbed do about 5 gpm and can take water up to just below boiling, so I wouldn't use it to pump finished wort. They were new, and a really good deal, so now I have a decision to make. 2 of these pumps came out less than a March Pump.
Before you say it, yes I have spent more than the cost of a March pump by now.
I liked the self priming aspect of the perstaltic - the cheap mag drives are half the cost of the peristaltic.
I will either resell the pumps I don't use - or put together another system and list it on craigslist.
