I bought a CIP ball from brewershardware. The thing is larger than I envisioned, something like 2" diameter with a 1" threaded connection. Can I possibly hope to pump enough water through this thing to blast my conical clean? Or do I need something more like a 1" diameter?

How big is your pump?

The pump I am trying to use is a 12V harbor freight marine utility pump, supposed to pump 260gph at 50psi. I'm using hoses for a washing machine, probably 1/2" ID and only 6' long.

You can convert your pump's maximum head rating to an effective PSI rating and see if you have enough horsepower to drive it. I have a LG 5.5-MD-HC and I decided it didn't have enough power to really drive that bad boy.

From the product description on brewershardware:

"Rotating CIP Spray Ball 1" FPT Connection. Operates on 15-100PSI, 40-60PSI is recommended. Ball diameter is 2"."

One foot of head is equivalent to a pressure of 0.433 psi

Give it a whirl! I will be interested to see if it will work for you. Been trying to find a CIP sprayball that's a little bit smaller scale that this one, but it would work for some of my uses if you're able to drive it with a pump like that!

This is the pump:
12 Volt Marine Utility Water Pump

Its maximum lift (=head?) is 35ft, does that mean it will only produce 15psi? I am not understanding this very well. I'm looking at other larger sump pumps that pump more gph but their maximum lift is even less than this little pump.

Their output assumption is probably 1.5" or 1.25" ID PVC pipe...

The connections are either 3/8" NPT female or male garden hose, so maybe they're using a garden hose ID as an assumed output.

I'll give it another whirl tonight, hopefully it will actually whirl. I ran the pump whith a battery charger and it didn't push quite hard enough to spin the ball but I'm hoping an actual battery will give better results. Will post back on the outcome. I am thinking your LG pump has to be a lot stronger than this little thing.

TBH, I am now rethinking and recalculating. Also, I believe my understanding of feet of head also needs some refinement... off to the interwebz.

edit: Nope, only rated up to 17.5 psi (40.5 ft of head).

I posed the question to my engineer buddy (also a brewer) and he seems to think this pump will work. He said the 260gph at 50psi means theres 50psi coming out of the pump head, and that this will be lessened somewhat by the 3' or so of head to get to the top of the conical, and that should still be enough to run the spray ball (40psi).

I guess I'll see tonight, now I want to get off work early! But that is nothing new.
