Thank you!
I've done a quick mod to one of my currently un-used pumps, it's a cheap chinese pump rated at 2000L/H and 2m head.

and I've done this to it




yes that is blu-tack plugging the old centre hole.

of course since these pumps can spin in either direction I had to turn it on and off a couple of times before it span in the "right" direction (ever since I did the impeller mod on this pump it splutters and carries on a bit untill it finally decides to fire up)


spinning in the wrong direction, also very similar to pump with centre outlet;


spinning in the correct direction;


actual performance change through my "cathar style" micro channel block is nothing short of amazing.

pump pre-mod, 1m of 1/2'' tubing my block = 660L/H
pump post mod, 1m of 1/2'' tubing my block = 1120L/H

almost double the flow!
