It is a simple submersible pump. In my case I use a Superior 1/3HP, 91330. And then I use it with the standard PVDF rotating spray nozzle that a lot of people on here use for CIP and you can pick up from McMaster. This ensures full coverage.
As for PET carboys - assuming you are using something like a Better Bottle: max temp is 140. Most household water isn't this hot and you don't need the water to be this hot for a good cleaning. Run a bit colder, and longer. Hot water just helps speed up the process a bit.
Hope this helps.
