Rated 5 out of 5Â by RoryFire 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.

Rated 5 out of 5Â by agydrvr Great Central Heating Pump
I bought this pump to replace an early Grundfoss 15-50. On Line, Screwfix call it a "Commercial pump". Take no notice, it is an extremely quiet and sophisticated central heating pump suitable for most domestic situations and is a direct replacement at 130mm port to port and a 5m head. With variable and fixed speed settings and 'A' rated low power consumption. I have only given it 4 stars for reliability as it has only just been fitted, although the manufacturers seem confident with a 5 year warranty! (Grundfoss only offer 2 years).

Rated 5 out of 5Â by Whitevanman2 Super quality!
I needed a new pump for my underfloor heating and couldn't wait for a replacement Grundfos from plumbers merchant so had a look at Screwfixand and found this.This pump comes with some nice features like variable speed and digital display and a handy 5 year guarantee.Will certainly use similar if ever needed again.
