Damn I wish fleabay actually had a search engine.

Look for "Little Giant" brand, that's what I use on my flood coolant system, it has worked very well. They make several types, I think the best is the kind with the motor above the fluid, and a seal-less shaft that runs vertically down to the pump. So, only the actual pump housing and impeller are in the fluid.

See the last picture here :

The blue thing is the plastic cover to keep drips out of the motor. The white cylinder is a filter to trap the chips in the returning fluid.
