I was seeking some info on them a few days ago, the biggest problem is their dimensions, the only one small enough is UP 15-14 B 80 (see the
www.grunfos.com), the price is about 130 euro here. The alpha series is more pricey than their UP or UP S series, and the guy I was talking to said that either I can buy a Grundfos or buy a same size/type/head/pipe connection pump of some other manufacturer at about half the price. Didn't decide yet, I'd like to see this pump 'in person' to get the feeling of the size and possible instalation problems considering the pipe inlet/outlet position.
Damn, still want a Iwaki, but no resellers here...
