There are a few considerations in making your hose diameter decision. Here’s a quick refresher on the differences between 6” versus 8“!
The major part of this decision comes down to pumping distance. For example, if you are running 1,500 gpm at 200 psi, a 6” hose will transport manure one mile whereas an 8” hose will get you 2.8 miles.
In comparison, if you were wanting to move manure one mile through an 8” hose at 200 psi, you would be pumping 2,500 gpm.
The other thing to consider is lowering your pressure to reduce stress in volatile areas. If you were pumping 1,500 gpm through a mile of 8” hose, it would only take 70 psi.
