Oil in water pump? Oil pump?
 

I'm concerned with my water setup as of now. I've been pressure testing on water for the last few days, and even tho my system is more than strong enough I had a major blow off of a tube, and I'm just not satisfied with regular water and or methanol anymore. I'm looking into other coolants and with respect to this section of the forum I have a few questions.

Has anyone ever ran oil in a water pump or can tell me for certain this is flat out stupid? (Im talking about a nice Iwaki... Something expensive)

Would It be possible to run an oil pump in the loop?

Is oil stupid in a loop? I would think I might have more of a seal problem.

Also please keep in mind there are low viscosity oils out there too, but maybe anything more viscous than water is a bad idea. I'm also aiming for a chilled water solution so low temps ie -50c are a must. Thank you in advance.

not exactly stupid, but water is used because it is the best. Better than just about every oil out there (or indeed anything else)

I did a calculation (using a correlation formula) for FC77 (flourinert) some time back and rejected it on the grounds that performance wasn't there.

look around i'm sure there is something.

NB: The whole point of using a dialetric is so you don't need a waterblock just squirt it on the cpu die.

Can you explain how you got a blow off? What pressures have you been testing? Hose clamps?

Otherwise, most mag drive pumps don't take well to visquous liquids, even if insignificantly more viscous than water.
