I included pressures delivered by 3 different pumps, the irrigation pumps used 1 inch tubing and the March 809HS used 1/2 inch tubing.

Results:
March 809HS - Produced 0 PSI and would not rotate the spray ball; Just and FYI when the outlet valve is closed completely the pump only generates 3PSI - Way less than the rated 6.7PSI. After in-service for 10 years never rebuilt a new or rebuilt pump might perform better. Pump not recommended for use with this CIP ball.

Wayne PLS100 1HP Irrigation Pump - Produced 3.5 PSI, rotated the ball just fine with 135 Degree PBW and Sodium Hydroxide solutions. In-service for 5 years. Works just fine in a 45 gallon tank and 30 gallon fermenter with this CIP ball cleaning all Boil Trub and Krausen.

Barracuda 691-1808 1HP Irrigation Pump - Produced 8.5 PSI, rotated the ball just fine with 135 Degree PBW and Sodium Hydroxide solutions. Brand new 0 in-service year(s). Works just fine in a 45 gallon tank and 30 gallon fermenter with this CIP ball cleaning all Boil Trub and Krausen.

I mostly closed off the outlet valve on the irrigation pumps and the pressure easily maxed out the gauge.

If the CIP ball did not have as many slits in it for water to come out maybe the the March 809 Pump could run it. I am looking to get a Chugger T-Max pump and see how it performs, I will update if I do.

I have the ball mounted sideways in my MLT for sparge with the bottom of the MLT 6" higher. It does not rotate (as I desired) and disperses in a gentle 6-8" circle.

I added one of these to my Mark's Keg Washer and it works great. The submersible pump puts out plenty of PSI to rotate the ball and thoroughly clean my kegs.

I don't understand what this product is. I am using a keg as a mash/lauter tun. If I mount this with the ball pointing down and use a March pump to pump sparge water through it, what will the spray pattern look like and will it cover the entire grain bed?

CIP stands for clean in place. The purpose of these balls is to clean equipment without having to dismantle it, just like a production brewery. I suppose it could be used as a sparge sprayer, but that is not the intended purpose. It is designed to power wash with a pump pushing the cleaning solution through the CIP ball. Lower pressure applications, like using a gravity feed from one vessel to another, will not make the ball spin.
