4" x 3" Hydraulic Driven Water Pump W/ Mounting Flange

If you are considering running a system hydraulically there is only one answer and that one of these pumps. The 13 tooth B- 2 bolt flange mount is the only way to go. The other screw on style mounts always wiggle loose and fail ruining both the pump and hydraulic motors. This ARMS pump is made in the USA !
