Got a question about the pump you listed. I noticed in the specs it was only rated for 18psi but most of the spray balls I've seen are supposed to need 30-60psi. Am I interpreting something wrong?

I don't know much about fluid dynamics. All I can really tell you is that with this particular pump and spray ball combination, there is a ton of cleaning action happening.

I'm sure more pressure wouldn't hurt, but at this scale (the diameter of the brewhemoth is very small) its really already overkill.

I don't doubt it cleans well and wish I knew how to calculate it, just would make evaluating which pump to buy easier.

Looking on ebay, this would seem like a good buy if I knew something about the quality:

1HP Stainless Steel Jet Shallow Water Booster Pump Pressure Control Controller

I've spoken to that vendor...he's the guy listing 104F as the temperature limit of that (and all of his) pumps.

Good to know, that keeps me out of trouble.

That pump won't do for that big of a cip as its only rated for 948GPH, which is about a litre per second. you're going to want a higher flow like 2500+GPH. don't worry about the pressure rating. That's just for head pressure, and you shouldn't have much with an open flow cip ball.

The temp rating is important too. high heat sump pumps aren't cheap though unfortunately. here's mine : http://www.libertypumps.com/Products...?p=55&s=4&c=14

Yeah, definitely getting pricey, but at least it looks cheaper than the freezer and all the fittings that I have to sneak into the house for these things.

FYI, 104 degrees F is equal to 40 degrees C, which I have seen listed on many pumps as the Max Ambient Temp rating. This has nothing to do with the fluid passing through the pump. It refers to the max ambient temp (room temp) allowable in order to still achieve proper cooling for the electric motor. That seems like a standard Max Ambient Temp for many of the pumps I have seen that pump up to 250 deg F fluid.

Best to confirm with the pump manufacturer just in case.

Agreed there is almost nothing that should or can be assumed when it comes to specing out pumps. Unless you get into higher dollar pumps most don't go over 120-150F range. You can run higher but expect the pump to fail sooner.
