One thing I found is the smaller pumps arent very good for whirlpooling if you use a 90 degree elbow at the end. I tried an open 1/2" elbow with no other restrictions and it dramatically cuts the flow down.
I actually use a clip to attach silicone hose to the inside of my bk now at a 75 degree angle or so to whirlpool and its much more effective.
This is really the only restriction I have found with the smaller pumps. Otherwise they flow great and are more than enough for transfer and mash/sparging.
