Submersible pump. 396 Gallons per hour, 25 W motor, 1.5M=4.9 ft power cord

Possible homebrew uses: Recirculating draft line cleaner build or as part of a recirculating wort chiller setup.

I use a similar style pump (although different model, manufacturer and specs) in my Recirculating Draft Line Cleaning Build.
