Ordering a sludge pump...gpm question

Hey all, I’m investing in a sludge pump. Right now i’m running 4 gpm, but I play to upgrade to 5.5 gpm by spring. If I order a 5.5 gpm sludge pump, will it work temporarily with my 4gpm unit? I figured it would be okay, but never hurts to ask for advice. Thanks for any help!

Should be fine, but ask your distributor you’re buying from. At worse, you just have to buy another tip for it.
