IF you're on their web site looking at the pics, it's huge, I know. The pump inside that housing is actually quite small. That's what I meant when I said they need some retrofit for our application. From the intake to the back of the pump itself is roughly 7", it's 5" wide and about 3 1/2" thick. I doubt you would need one that big. With no head it's rated at 2900 gph so going with something like the Maxflow1500 might be enough for you. It is kind of a weird shape though, so it may not fit your needs. Just thinking outside the box
