Not familiar with the South Bend, but looking at the specs a 12 3/4 aluminum wheel with a 220v 9A motor (more like 1 1/2hp) seems a lot underpowered to 6” pipes unless your run is very short. And 6” into 3 – 4” is total BS. Surface area of a 6” circle equals surface area of 2 1/4 – 4” circles. Hook up 3 – 4” hoses at once and they loose 25% suction. Not good for the motor either unless they have a built in restriction at the blower (I bet they do). Not sure this is much of an upgrade. I would pass unless it barely used and super cheap. My 2 cents.
