Peristaltic Pumps, What to get?

[tcmfish]

So I have been doing some searching for a peristaltic pump to control the effluent of a calcium reactor.

It seems those who have done this recommend the Cole Parmer Masterflex pumps, but new they are insanely expensive, and used on ebay I don't know what to look for and lots of products haven't been tested which makes me nervous. Some people claim to get used pumps for $100 or $150 but when I have been searching lately most of the controllable pumps seem to be at least double that. Maybe you can control fixed flow pump?

Also, McMaster Carr has some in $200-$300 range, but would it be a bad choice?

The litermeter has also come to mind and some people report of using it, but then never report back. Can anyone comment on its effectiveness? It seems like it might be best used to suck water through the reactor. Thoughts?

If anyone has any other recommendations as well I am open to looking at other brands. Thanks.

Well I will be getting in the same boat as you. Problem with peri pumps they cannot be ran 24/7. I had a Deltec one 32ML/min 24/7 and it would make a lot of noise so it is back at Deltec. One of the mods recommended reef filter peri pumps I did put it down on my Bookmarks but this darn apple system just buries it and may take a while to find. Something to also consider is what is the bar pressure your reactor can handle mine is .05 not very much.

I have one of the BRS pumps. It is a little over a year old and has been great for me. What pump rate are you looking for?

Masteflex pumps are designed for continuous duty and work great. Look for 75XX model with Easy Load pump head. You can find them for under $150.
