That's the idea, but 11.6 GPH is too low. For a typical 5 gal mash you need variable speed up to 1 GPM. The March/Little Giant at 7 GPM is too damn fast, it's hard to throttle accurately, and I damn near stuck my last mash!
Cole Parmer makes a peristaltic pump called Masterflex (I'm giving away my research here) that rates up to 4 liters/min, and it has stackable heads so you can run two at the same flow rate and fly sparge very precisely.
Masterflex pumps come 60-600 RPM, and in 0.1 ml/min to 4L/min versions. What you want is the 600 RPM model with the big tubing heads. The problem with the Masterflex pumps on ebay is that they're mostly obsolete and the sellers don't know squat about them, and even when they give the model number the Cole Parmer site is hell to navigate and find info on.
One of these days........
