inline electric water pump

I need some help. Im looking for a pump to put inside the radiator hose to circulate water between rounds. 12 volt or possibly 110. Automotive or maybe a pond pump?

I'd suggest that you look into some options. The 110 V stuff is probally in a Grainger catalog or a McMaster-Carr catalog. The 12 V in-line pumps, you need to look at Meizerre's catalog.

Hope this helps,

they have a 12V and 120V. this is the 12V version.
usually you can get stuff for a lot less than listed price with these guys.
