grundfos#pump number

[dancn]

I'm looking at Grundfos UPS 15-50 pumps on web and I've finding several different numbers
for which seems to be identical 5m pumps,
numbers I'm finding are 96281442, 96281448, 96281446,
Can someone help explain the differences,

Surely the pump if has the same specs then its the same ? Maybe check out the website and see if theres a major design difference which would make you buy one over the other !

Have not checked No.s but most likely they will be the same pump head but in different body lengths you can get ups 15/50 that are 130mm or 180mm between the centers you can also get different outlet / connection sizes we tend to use a standard size in this country for domestic CH pumps but abroad & in combi / system boilers you can get 1/2", 3/4" etc.
Hope this helps, check the full pump spec.

I can find at least 6 numbers for 15-50 130mm all in the range 962814**.

Some are single trade boxed, some are retail boxed, some are from a trade multipack.
All are bare pump no valves.
All are 130mm long with 1 1/2" union size.
All are 240v
Can't find any info on Grundfos.
I've had various numbers before.

Just buy the cheapest 15-50 130mm you can find.

The (N) stainless and (B) bronze are more expensive and are not required for heating purposes.

So It's possibly down to how they are sold?
yes as above the 3 I found all 130,5m 15-50s, very little info from grundfos
I need 4,running from a manifold, hence trying to keep things consistant.

alot of manufacturers now warranty their products via serial number/ codes and not to receipt or when bought.
