Good pumps. I have used a few of these now after getting cheesed off with several alpha2 going wrong just after the warranty runs out. No problems so far and even used one in my own house. 8 Feb 2015

Worst punp ever !!! Wore out after 2 months, pay the extra and get a decent one. 30 Nov 2014
Good standard 15-50 pump Bought this to replace failing Grundfos Alpha+. As others suggested, not sure where "commercial" comes from - appears to be a standard 15-50 pump with 130mm from flange to flange. Comes with gland washers. The Grundfos electric plug fitted too, which was handy. So far (a week) working well, noticeably quieter than the Grundfos. I've never thought about the power these things use, but running at around 20W the Wilo seems very low. 1 Nov 2014
