Second JamesBednar on the mash pump .. We use Waukesha Lobe pumps that are all stainless in 1-1/2, 2, and 2-1/2 they get VERY Heavy .. With motor and drive .. my 2-1/2 on the cart weighs 450 lbs..... These things will pump very heavy mash ... I bought mine off ebay in component level and built carts, added motors and drives ... Do some research , you can buy 3-5hp Allen Bradley or GE drives starting @ 15.00 ... Pumps usually in the 300-1000 price range .. Gear motors 1:4 to 1;6 ratio 100-300$$
