This brings back memories of my first distillation ever.
When I bought a distillation apparatus I thought I didn't need a pump as I already had a small pump of the kind used for spraying water on the windshield in cars. Little did I know that those kind of pumps are really not designed for continuous operation, so when I actually ran my first distillation, the pump melted. It was at that time, in the middle of a nitric acid distillation that I thought "shit now I need a pump".
I've always tried to be safe in the lab, so I had set up a NaOH scrubber for NO2 gas, but I didn't yet know what a suckback trap was and why I needed one, and when I hastily turned off heating I totally forgot to disconnect the scrubber. It was at that time that the ten mL or so of nitric acid I made for decapping integrated circuits quickly reverted back to the soduim nitrare I started with. Fun times.

Not visible in the picture but the water goes out to a air over water heat exchanger with a couple cooling fans.

In fall and winter is when I do most my chem as it is to cold out side to do any thing, so water temp is at or below 0c with that small exchanger running.

Sometimes, it is possible to buy a water pump that is intended or small fountains. I used that as a replacement when my condenser pump broke and it works fine.
