I just pulled the trigger on 2 Little Giant 2 MD pumps on Ebay for $55 dollars each. The auction is for $78 each but I put a best offer at $55 and the seller took it. There are 2 pumps left available on his auction.

http://cgi.ebay.com/LITTLE-GIANT-2-M...item2ea9b711b7

Anyone interested should take a shot at $50 each and see what happens.

Cheers,

Copster

post back here after you've used them for a while and have good feedback.

The company lists those as having a temp rating of only 150*F, but I and some other folks suspect they will hold out at higher temps.

I bought the 3-md-hc, but if find myself wanting a 2nd pump, I might go with the 2-md for the second one.

The 150 degrees has me skeptical. Strike and sparge water are higher than that. I'm not saying that it won't work, but I'd think that pumping hot wort through a counterflow chiller would prematurely lead to failure.

Thanks to Walker for his link on another thread.
I also have this same pump bought off ebay awhile back.

Found this page of facts about polypropylene:

Baldy_Beer_Brewery, I agree with you and it might lead to premature failure, I relied on the fact about polypropylene from Dynalab Corp on this one, hope that they are somewhat reliable and that I can use the pump at hotter temperatures and less pressure then the given max pressure for the pump. Only time will tell I guess.

when we were discussing the temp ratings on these things, it came down to a matter of pressure and temp, and not just temp. I don't remember who on here said it, but they stated that the temp rating is related to the max psi that the pump can handle. At lower pressures, the temp rating would go up.

For what it's worth, the 3-MD-HC (which is the one that many folks use as a substitute for the march 809) only has a temp rating of 200*F, but folks report absolutely no problems with them after many batches where they pumped boiling liquid through them.
