Considering options for a pump to handle CIP for sanke fermenters and some larger plastic conicals. I came across this pump;
Anyone have any experience with one of these?http://www.harborfreight.com/1-hp-1-inch-shallow-well-pump-with-stainless-steel-housing-47906.html
Check out on-demand ag sprayer pumps. You probably don't need a big 1 hp well pump for CIP. A 60 psi pump capable of 2 to 5 gallons per minute should more than satisfy your needs.
Harbor Tool and Freight has this 1HP pump on sale for $89.00. Any Idea where I can get something cheaper that will do the job?
They all look like plastic wet ends, how do they hold up to 180 degF Caustic?
The Shurflo models say they're good up to 170, and they have NPT ports. They're all for chemical applications.
For comparison, this guy's using a March 809.http://www.homebrewtalk.com/f11/cip-pump-question-180412/
March pumps don't supply much pressure.
I wouldn't think a March could keep up.
Me neither...but that guy likes his.
