Guys, I did a little research on the sump pump I bought and thought I should share the information I found.
It appears as though most sump pumps that are not rated for hotter temperatures (most rated for 70ish F) are filled with oil to aid in cooling the pump.
The pump I bought, flowtec, has a warning on their website which states that if the pump overheats, the oil seal could blow and cause oil to leech into the water being pumped.
This made me wonder if this very thing has already happened to me, and maybe you guys seeing as though we talked about oily water.
I've decided to return the flowtec pump I bought, and go with a pump actually rated for hot temperatures and able to push 50-60GPM minimum.
The pump I'm going to order up is a Liberty HT40 series, rated for 200F and moves 60GPM. They are fairly expensive @ $290, BUT this pump is good quality, good warranty, and will run within spec.
Please don't use this pump. The warning that the pumps electrical cord has lead in it is concerning enough. And it also specifically says not to run chemicals through it. A thermoplastic submersible would be a better choice before this pump.
Sorry apparently the preview button means post hence the double post!
Every extension cord I've seen has a lead warning.
How about this pump?

Not all of them - my thermoplastic is rated for 140. It just depends... the one thing to your benefit is the shutoff doesn't come until 158. The only question is what materials are on the inside of the pump? The housing is stainless, but what about the impeller?
The liberty HT41M sump pump I bought a couple of weeks ago works extremely well. AT 60GPM and 200F rating, it blasts the inside of my brewhemoths. Very much worth the money.
The hardest part with this setup was finding hoses capable of handling the 200F that the pump is rated for!
Hi Fakr-
Sorry to resurrect this. Does this pump still work OK for you? It has some parts made of cast iron... does PBW make this rust?
