Suppose the subject says it all. If so what:
Pump/Model
Compressor Model
Would you do it again?
I've read and read here about various pump that folks are using. We're looking to purchase two new pumps, one small one for spirits (looking at Yamada DP-25F) and one to move mash. There seems not to be a perfect mash pump. Although not rated as such, we've used our US FIP to pump hot (about 185°F) mash without (knock wood) incident. Interestingly enough US FIP does have a high-temp impeller that's rated to 204°F. SO... the US-FIP we were about to pull the trigger on is $4k.
If we purchased a large, 1.5" AODD (say the Yamada NDP-40BST-NPT at around $2,700) and accompanying compressor we're looking at about $5k in addition to the electrical costs associated with compressing said air. BUT we could use it to pump our spirits as well. Lastly, can we save any money and get a better product by building our own FIP (cart + motor + VFD + pump head).
All thoughts / comments / advice appreciated
