Homebrew PCBs

Grant,

The part number for this pump is CP-6500. Another source is Johnstone 
Supply. Their catalog number is B80-943. Catalog price is $16.59 
(US).   www.johnstonesupply.com

The catalog info says this pump can handle "mild acid-alkali 
transfer". Has a four blade nylon impeller molded to the shaft. This 
must be a new version. The older Kepro etchers had a modified PVC 
impeller and shaft since these parts used to be metal. This pump will 
move 225 gph at a 3 foot head. This pump will move a lot of etchant, 
just ask anyone who accidently opened the lid of a Kepro ecther while 
it was running !!!
