Hi guys, first post!
After lurking and reading through this entire thread a couple weeks ago (yes, the whole thing), I decided try a couple cheap chinese pumps.
I just received 2 of these 24VDC pumps from eBay (one is just a spare):
Eo56 pump
also at AliExpress:
Eo56 (TK1226) pump
They claim to be food grade, I took it apart, and it looks simply and well built. It has a brushless sealed motor, 16 lpm (~4.3gpm) flow, capable of 6M of head, and male 1/2" npt ports (actually looks more like BSPP straight thread).
I will be doing my first AG batch this weekend in my single vessel keggle BIAB system. I'm going to attempt using this pump for both recirc. during mash, as well as for whirlpooling during immersion cooling. I will try to take some pictures, but either way will report the results. Thanks for all the guidance thus far guys, this is a really great community.
